Intellectual Ventures launched a public database in 2013 providing details on 33,000 patent assets it owns. An analysis was conducted of IV's portfolio based on this data. The analysis found that over 50% of IV's patent assets will expire by 2021, with over 80% expiring by 2024. IV's portfolio focuses heavily on electrical engineering and computer technology, with these fields comprising over 80% of the patents. The international component of IV's portfolio is about 31% of the total, with most foreign patents located in Japan.

All eyes on IV
By Kent Richardson and Erik Oliver
At the end of last year, Intellectual
Ventures launched a public
database providing details of
33,000 patent assets that it
currently owns and manages,
allowing an in-depth analysis of its
portfolio for the first time
Whats inside IVs
patent portfolio?
In December 2013 Intellectual Ventures (IV)
took a step towards transparency by publicly
listing about 33,000 of its patent assets,
representing 82% of its patent monetisation
portfolio (http://patents.intven.com/finder).
Analysing IVs portfolio has now become
a tractable problem. This article examines
what is in the portfolio, what IV buys and
what IV did after the purchases.
After analysing the portfolio, we were
able to answer specific questions such as
the following:
When does 50% of the portfolio expire?
(2021)
What is the preferred priority date at
the time of IVs purchases? (Between
eight and 14 years)
What percentage of IVs portfolio are
continuations? (8%)
When did IV increase its litigation? (In
2011 and 2013)
We believe that companies can use
this knowledge to compare practices in
their own patent development and buying
programmes. We also believe that the
analysis can be used by companies to create
fact-based arguments for use in licensing
negotiations. Finally, the data suggests
that cross-licences, springing licences on
transfer to non-practising entities (NPEs)
and micro-pools may reduce the risk of
NPE assertions.
We kept our analysis targeted on
the facts presented in IVs monetisation
portfolio and did not let it stray into
discussions about IVs business model. We
used public information in the preparation
of this paper IV was not consulted on the
data or the analysis.
IV was founded in 2000 with the stated
purpose of reducing patent risk for its
corporate investors and assisting companies
and individual inventors in monetising
its inventions. Since its founding, IV has
reportedly raised over $5.5 billion in capital,
a large portion of which has come from
corporate investors in the high-tech space,
such as Microsoft, Intel, Sony, Nokia, Apple,
Google, Yahoo, American Express, Adobe,
SAP, NVIDIA and eBay. Of note, Google did
not invest in IVs second buying fund and it
has been reported that Apple and Intel are
not investing in IVs third fund.
IV reports that it has spent about $2.3
billion buying and developing patents
through its patent purchasing programme
the other $2.2 billion raised would have
been spent on operations and management
fees. The vast majority of IVs revenue does
not come from making products or licensing
technology to enable the manufacture
of products comprising the inventions
captured in its patent portfolio. Rather, it
comes from licensing its portfolio to other
companies IV is the quintessential NPE.
Which portfolio and what assumptions?
Figure 1 shows the relationship between
the 70,000 assets that IV reports it has
purchased or developed, IVs current
40,000 asset monetisation portfolio and
the public list of 33,000 assets that IV
released in December 2013. To begin our
analysis, we first needed to understand what

also affirmatively identified assignments to
IVs holding companies. We used a mixture
of publicly available lists of shell companies
from Aaron Greenspans Plainsite and IP
Checkups, as well as our own analysis.
This process resulted in the identification
of about 17,000 US assets as part of IIF.
We were able to determine the relative
proportion of IIF to ISF and IDF within
the US monetisation portfolio. We then
scaled that portfolio back up to the entire
monetisation portfolio, compensating for
international assets within the portfolio.
Because of rounding, not all of the columns
in Figure 2 add up perfectly. Unless
otherwise noted, all analysis was done
using the identification and scaling method
described on the IIF assets.
For simplicity during the calculation of
expiration dates, we assumed 20 years of
life after the earliest priority date and did
not factor in term extensions or terminal
disclaimers. Additionally, as IV did not
list its expired assets, our data provides
a snapshot of the IV portfolio of live
assets as of December 2013. IV states that
70,000 patent assets have been bought
or developed meaning that 30,000
assets are no longer in the monetisation
portfolio. Therefore, any per year analysis
reflects survivorship bias only those
patents that are still alive are in IVs public
monetisation portfolio. This survivorship
bias makes extrapolations about IVs
buying activity in the early years more
difficult. Finally, IV published its list of
assets on December 13 2013 and, as such,
this list may not include assets purchased
beyond late 2013.
IVs monetisation portfolio today
To begin our analysis, we examined the
current composition of assets in IVs
monetisation portfolio. We considered
questions such as the following:
When does the portfolio start to expire?
What does the international portfolio
look like?
Which technologies are represented?
is in IVs patent monetisation portfolio.
Put another way, how many of the 40,000
patent assets in IVs current monetisation
portfolio should be allocated to its buying
activities, as opposed to its investment and
development activities?
Turning to Figure 2, IVs monetisation
portfolio is spread across three different
fund categories. The Invention Investment
Funds (IIF 1 and IIF 2) primarily represent
IVs purchased patent assets. For the
purposes of the analysis, we group IIF1
and IIF2 together as one fund, IIF. We have
also categorised patent assets to include
applications, pre-grant patent publications
and patents. IIF3 is currently being raised
and we believe that no IIF3 assets are
included in the public portfolio.
The Invention Science Fund (ISF)
contains patent assets that IV has
developed in-house. Finally, the Invention
Development Fund (IDF) contains patent
assets created through RD funded by
IV in exchange for the right to license
any resulting patent assets. Interestingly,
IDF assets tend to be university licensing
deals. These three fund groups make up
approximately 80%, 10% and 10% of
the monetisation portfolio respectively.
Although ISF and IDF are interesting in
their own right, for the purposes of our
analysis we chose to focus on IIF because
this is where IV spends the majority of
its time, money and effort. It is also the
portfolio that we believe poses the highest
potential infringement risk to other
companies.
To focus on IIF, we wanted to identify
the monetisation portfolio assets directly
attributable to the IIF portfolio. Referring
to Figure 2, we first started with IVs public
list of 33,000 assets. We then identified
US assets in that list and removed any
duplicates. Focusing on US assets enabled
us to look at the current ownership and
history of ownership of the patents. Next
we removed assets assigned to laboratories
and universities (IDF) and to IVs science
fund (ISF), a separately listed assignee. We

companys perspective over time. For
example, seven years from now in 2021,
how many of IVs patents would you need
to license? Similarly, if calculating a licence
fee for a capture licence, how many years
of revenue should be considered under the
licence and at what royalty levels?
International patents
Turning to the foreign asset profile of IIF,
we used the identified US patent assets
to locate the entire International Patent
Documentation Centre (INPADOC) family.
This methodology will overstate the size of
IVs foreign IIF portfolio as a result of:
double counting INPADOC counts a
patent publication and a patent grant as
two assets rather than a single asset; and
INPADOC listed assets having lapsed
before IVs acquisition of the patents.
Nonetheless, this approach was used
because the IV-published lists could
not easily be used to analyse IIF directly
as opposed to ISF/IDF due to a lack of
international assignment data.
The data indicates that IIF has
approximately 10,000 foreign assets (Figure
4). Alternatively, looking at the foreign assets
and using the scaling-up approach described
in conjunction with Figure 2 results in a
number closer to 7,600 foreign assets for IIF.
Thus, our methodology provides an upper
boundary of the largest potential scope of
the foreign IIF portfolio. We believe that a
more detailed picture could be constructed
through cross-referencing the IV-provided
list with the INPADOC data to identify the
IIF-specific patents.
Overall, the international component
of IIF represents 31% of the portfolio and
demonstrates a large investment in US
patents with INPADOC families having
Japanese patents and publications, followed
by Patent Cooperation Treaty publications,
and European patents and publications.
The next largest international country is
Australia, which we find surprising given
the relatively small size of that market.
One possible rationale is that during IVs
buying, Australia had a judicial system more
favourable to patent holders and NPEs.
Other than China, there were few assets
from the BRIC countries (Brazil, Russia,
India, and China) in the portfolio.
The technologies
Figures 5 and 6 show the technology sectors
and fields that we were able to determine
from the US assets and the International
Patent Classification (IPC) codes. Specifically,
each patent is assigned one or more IPC code
by the European Patent Office. IPC codes are
What is the portfolios lifespan?
Like many of our clients, we are
interested in understanding when the IIF
patent portfolio expires. This lifespan
information is helpful in understanding
the long-term risks that a company faces
when negotiating with IV. By knowing
when the IV portfolio expires, a company
can modify its negotiating position. For
example, knowing the lifespan of the
portfolio points to the length of time
for which a licence may be required, and
informs what a licence today versus a
licence three years from now might need
to cover and the magnitude of exposure to
potential back damages.
Figure 3 shows that more than 50% of
the IIF patents will expire by 2021 and more
than 80% by 2024. When evaluating your
companys exposure to IVs portfolio, we
think it important to analyse your specific
technology area and assess it against the
expiration dates of the relevant portion of
the IIF portfolio. See below for more on the
portfolios technology distribution.
Figure 3 is generated from the scaled-
up set of calculated expiration dates. Even
though term extensions and terminal
disclaimers are not accounted for, we
believe that this is a good approximation for
the purposes of our analysis.
Bear in mind that Figure 3 represents
the surviving patents in IVs IIF portfolio:
30,000 assets have already expired or
been transferred out of IIF. Looking at
the expiration years, we can imagine
that the left side of the graph would look
substantially different if we had data on all
of the assets ever held by IIF.
From a practical standpoint, consider
where the distribution of patent value
is from IVs perspective versus your

hierarchical codes that can be used to classify
patents based on different technologies to
which the patents relate. We focused on
the use of IPC codes because the World
Intellectual Property Office has standardised
a taxonomy of the tens of thousands of
IPC codes, using 754 unique IPC roots, into
five technology sectors which contain 35
technology fields (see Ulrich Schmoh, Concept
of a Technology Classification for Country
Comparison: Final Report to the WIPO, 2008).
We analysed the patents on a per sector and
per field basis, removing duplicates for a given
patent. For example, a patent with three IPC
codes might fall into electrical engineering/
audiovisual technology (two IPC codes) and
electrical engineering/basic communication
processes (one IPC code). For our analysis,
despite having three IPC codes, this patent
is treated as belonging to two distinct fields
and one distinct sector. Another patent may
belong to more than one sector. For this
reason, the graphs total more than 100%.
Starting at the sector level of the
taxonomy, as shown in Figure 5, the vast
majority of assets are, unsurprisingly,
focused in the electrical engineering sector.
This covers significant ground and includes
a mix of semiconductor, hardware and
computer software innovation. Additionally,
several fields of interest also lie within the
instruments sector. For this reason it was
helpful to consider the top fields across all
of the sectors as shown by Figure 6.
Figure 6 shows that high-tech
represents more than 80% of IVs portfolio
based on the corresponding technology
fields, with computer technology
representing over 40% of the portfolio.
This is unsurprising given the significant
technology backgrounds of IVs founders,
the first corporate investors being high-tech
focused and the generally high number of
patents per product in high-tech fields. This
technology weighting is also consistent
with IVs initial vision of reducing NPE risk
for its early corporate investors.
When we examine the high-tech
sectors in more detail, we see more
buying in software over hardware. From
discussions with past IV buyers, IV
specifically pursued higher-visibility
technology areas where infringement is
often more easily detected.
Admittedly, IPC codes have granularity
and classification limits for understanding
IVs portfolio, but they form a useful
starting point for evaluating the impact of its
portfolio on the marketplace. For example, a
particular set of IPC codes relevant to ones
business can be used to determine when
the patents associated with those IPC codes

brokered open market transactions over
the last four years (18%). We find this
significant because the top-ranked results
are generally more interesting patents.
Survivorship bias may explain some of
IVs distribution. Specifically, over time,
IV would have an incentive to eliminate
lower-ranked assets. However, even in 2012
and 2013 (averaging 28% in the highest
rank), IV appears to have bought more top-
ranked patents than the average for open
market buyers (18%).
One would expect that an organisation
focused on buying and developing patents
would have more higher-ranking patents.
We would also expect informed open
market buyers to make similar decisions.
However, it is clear that open market buying
is either less selective than IV or being
carried out using additional factors not
built into our ranking system.
Figure 8 shows IVs rankings by purchase
year. Given survivorship bias in IVs public
list of assets, we would expect to see patents
bought early on to have a higher ranking. We
see this in a few cases (eg, 2002), but there
does not appear to be a trend. It appears
that between 2004 and 2009, IV bought
patents using other factors, such as quantity
versus price. In 2010 there was a marked
improvement in the higher-ranking patents,
with nearly 50% of those patents falling into
the top rank. Assuming that these deals would
have been structured in late 2009, it appears
that IV took advantage of the economic
downturn and bought more interesting
assets in 2010. Between 2011 and 2013 the
numbers returned to historical percentages.
IVs buying
Figure 9 shows IVs acquisitions by year. We
determined an acquisition year for each IIF
US patent asset and then scaled up to the
broader IIF portfolio.
When we overlay the resulting portfolio
with the economic turmoil of 2008, we see
IV purchases stepping up substantially during
relatively bad economic times. Between
2008 and 2010, IV probably found a lot of
great deals. That said, it did pull back from
its 2008 high. In 2009 one of the authors
interviewed Don Merino, who was just
completing his term as head of acquisitions
for IV. Merino asked what the author thought
would happen if IV pulled back from buying.
It is certain that IV fuelled the growth of the
brokered patent market and IVs reduced
spending had a significant impact on those
brokers. However as the authorsother papers
on the brokered patent market in IAM (eg,
Good things in small packages: the brokered
patent market in 2013, IAM 63, January/
will expire. Additionally, IPC codes that are
clearly outside of a particular technology area
of interest can eliminate a large number of
patents from deeper consideration.
We also believe that IPC code clustering
common sets of IPC codes assigned to
one patent might be beneficial as a further
analytical step. For example, looking at the
overlap of IPC code clusters relevant to ones
business compared to those common within
the IV portfolio can allow a more refined
view of the overlap to be identified.
How do IVs patents rank?
At the risk of igniting a patent quality
debate, we attempted to generate some
gauge of how IVs portfolio might rank
against other portfolios so that one
might start to make overall quality/value
estimates. We use our own automated
ranking system, which focuses on the
patents structure, claims, remaining life
and citations (for more details see http://
richardsonoliver.com). This allows us to
determine which portion of any given
portfolio we should look to first for
potentially valuable patents. The ranking
is not an absolute determination of the
value or quality of the portfolio, but it is
helpful in pointing to where to look first.
Importantly, the ranking is done on a per
US patent basis, so excludes publications
and international patents.
So how did IV do? Unsurprisingly,
IV had a higher percentage of patents
in the top rank than we see in typical
portfolios 28% of IVs portfolio is
in the highest rank. We compared IVs
purchases against our proprietary database
of over 1,000 open market brokered patent
deals. Figure 7 shows IVs top-ranking
assets (28%) compared to the top-ranking
assets we have seen purchased (2,516) in

chose the general shape of the histogram
in Figure 11, but chose a centre at around
10 years based on the 2012 and 2013 data.
Note that because of rounding, some
assets will show as having zero years of
remaining life.
February 2014) have shown, the market
remains robust and healthy independent of
IVs buying activities.
More recently, we see a substantial
decrease in IV purchasing. Figure 9 shows
an aggressive pre-2013 buying pattern.
However, Figure 10 shows 2012 and 2013 in
detail with a remarkable fall-off in buying.
Excluding February 2013, IV bought only 564
patents in 2013. It seems reasonable from
this data to assume that 2013 represented
the end of purchasing for IIF2 and that IIF3
had not yet been funded although it is
also possible that some purchases in late
2013 have not yet been listed by IV.
Remaining asset life
In Figures 11 and 12 we look at the remaining
asset life at the time of the assignment to
IV. This is one of the key characteristics that
our buyers consider when deciding whether
to buy assets. Note that survivorship bias
shifts Figure 11 to the right suggesting that
the purchases had a longer life than they
did in actuality (the green line shows what
the expected curve shape would be without
the survivorship bias). We see a distinct
preference for assets with between eight
and 14 years of life remaining. By buying
assets of this kind, we see that IV practises
what we have found to be true and has also
been reported in academic papers that
is, the value of a patent begins to show at
around 12 years of remaining life (eight years
from the priority date). Eight years after
filing, the technology has had a chance for
significant market adoption, has proven itself
as being compelling against alternatives and
is mature enough to stand a good chance of
withstanding a prior art challenge.
Figure 12 shows the distribution of asset
life remaining for patents purchased in 2013.
With an average of 10 years remaining, but
a distinct preference for between six and 12
years remaining, IV continues to practise
buying patents that have had a chance to
prove their value. Figure 12 also shows that
IV is willing to buy patents with a relatively
short remaining life. Closer analysis might
uncover deal-level linkages (eg, the shorter
remaining life patents came along as part of
a deal that got longer remaining life patents).
To calculate the scaled remaining asset
life, we used the calculated expiration date
of each asset in the US IIF asset computed
by adding 20 years to the earliest priority
date. We took the difference between that
date and the assignment date to IV. These
assets were then distributed by years of
life remaining and the distribution was
scaled up to the size of the IIF portfolio.
To estimate the shape of the green line, we

assets. If we further scaled up IIF to include
a proportional number of expired and sold
assets, we would expect $1.6 billion for 62,000
total IIF assets. However, if we were instead to
use the US patent data together with per US
patent price, we would estimate an IIF spend
of $2.6 billion for 62,000 IIF assets.
Our bottoms-up estimate between
$1.6 billion and $2.6 billion brackets
$2.1 billion in reported spend for IIF. The
$2.1 billion is derived from IVs recent
presentation at the 2014 USC Gould
IP Institute. Specifically, IV presented
spending of $2.3 billion on 70,000 assets
with $110 million for ISF identified. We
estimated IDF spending as comparable to
ISF, based on a similarly sized portfolio,
thus: $2.3 billion $0.2 billion = $2.1B.
One interesting aspect of IVs purchasing
is that it appears that the 2011 purchases
were more cost effective, in that IV spent
substantially less money for a larger number
of assets. This conflicts with the authors
intuitions that the 2008 downturn would
have provided the best opportunities to
obtain assets at a lower price.
Who were the sellers?
Since we see a lot of coverage in the press
about NPE activity and we hear many
companies complaining about IVs practices,
we decided that it would be interesting to
look at who is selling patents to IV. Figure 14
shows the distribution of assets per assignor.
IV clearly buys many small lots of patents
approximately 1,350 assignors have sold IV
fewer than 10 assets. However, these small
lots represent only 25% of IVs total assets.
Approximately 100 companies represent 60%
of the asset sales to IV with a surprising
list of the top 20 sellers of patents to IV:

IV spending by year
Based on the current portfolio, and
information presented by IV in 2011 about
IVs per asset spending, we estimated how
much money IV had spent per year on the
current IIF monetisation portfolio. This
analysis excludes the 30,000 assets no
longer in the IIF monetisation portfolio.
We calculated IVs spend using the
per asset purchase price listed in an IV
presentation by Merino for a Licensing
Executives Society meeting from 2011. Only
the per asset purchase price data from 2003
through 2010 was listed and we therefore
used the average of these annual prices for
the periods 2000-2002 and 2011-2013. We
first used the acquisitions per year analysis
above combined with the per year pricing
on both a per asset basis and a per US
patent basis to calculate the spend on the
32,000 IIF assets in monetisation.
Adding all the years together, we found
about $810 million of spend for 32,000

on the size of the entire IIF portfolio. IV filed
65% of these reissues. By any measure, 386
reissued patents is a large number a typical
portfolio may have only a few.
Figure 17 shows reissues by IV by filing
Looking at this list, we see a number of
companies in financial crisis or bankruptcy.
As a long-term strategy, it seems to us
that early cross-licences can prevent many
of the problems that companies later face
with NPEs which have acquired assets.
Along with industry practices of cross-
licensing, new models for reducing the
risk of NPEs are evolving. For example,
Google is promoting a licence on transfer,
where licensees receive a springing licence
when the patents transfer to an NPE. Other
options include Unified Patents Incs sale
to an NPE option, which helps to keep
patents out of NPE hands. Other defensive
aggregators such as AST, OIN and RPX also
provide helpful strategies.
To calculate the frequency distribution
of the number of assets per assignor, we
looked at every assignment, found a list of
unique assignors and then counted the assets
assigned by each of these unique assignors.
What did IV do after the purchase?
We next turn to the analysis of how
IV managed the patents after they
were purchased. We look at IVs patent
development work, as well as its litigation.
Continuations
Even when we look at issues around
survivorship bias, we see that IV files a large
number of continuations. Specifically, of the
17,000 asset in the IIF US-bought portfolio,
1,400 or 8% are continuations. Nearly
50% of those continuations are filed within
one year of the asset being bought.
Figure 15 shows when IV is most likely
to file continuations. Almost all of the
continuations are filed within four years of
purchase. Additionally, we looked at when
those continuations were filed relative to
the priority date, and a clear preference
exists from between four and 10 years (see
Figure 16). We believe that this further
illustrates IVs preference for developing
patents of high value between eight and 12
years from the priority date.
Continuations can be difficult to
track. An asset was determined to be a
continuation if the USPTO application date
was later than the date of first assignment
record to a company we determined to be
IV. This definition also includes divisional
and continuation-in-part applications.
IVs reissue practice 5% to 8% of all US
reissue applications
IV has demonstrated a pronounced interest in
reissued patents. Figure 16 shows that IV has
386 reissued patents in its published list. We
have not scaled up the reissued patents based

bought in litigation in, 56 separate patent
suits as of March 2014. Eleven of those
cases are in the name of one of IVs holding
companies.
Figure 19 shows the number of US
patent litigations filed per year for the IIF
portfolio. With almost no litigation before
2010, one wonders whether IV decided
that litigation was the only way forward in
many negotiations. Notably, IV initiated 33
distinct lawsuits in 2013 by far the largest
number to date.
We then looked at how often IV
purchased patents that had been litigated
and how quickly after the purchase IV
initiated litigation (Figure 20). We also
changed perspective from focusing on
the number of cases to the number and
identity of the specific patents in cases.
Figure 20 shows that IV bought many
patents that were in litigation or had been
recently litigated 242 US patents had
been asserted before assignment to IV. The
majority of these patents had been litigated
in the five years prior to the assignment
to IV. One open question is whether these
purchases by IV reduced litigation risk from
these patents for their corporate investors.
Of the 352 patents in litigation after
the assignment to IV, there is a clear
preference for litigating immediately after
the assignment 40% were litigated within
one year of assignment. There could be a
number of reasons for litigating so quickly
after assignment:
IV may have had an option on the patents;
There are a significant number of
litigated patents between three and nine
years from assignment; and
The early litigation may be a statistical
anomaly.
In order to determine the litigation
year. From 2005 to 2009 it appears that IV
included filing reissues after acquisitions
heavily in its buying strategy. This is
supported by our analysis showing that IV
filed 87% of its reissues within the first two
years of assignment the implication being
that IV planned to file the reissue when IV
bought the patents.
It is unclear whether IV reduced filing
reissues beginning in 2010 or whether the
long pendency of reissues is affecting the
data from 2010 to 2012.
Figure 18 shows IVs percentage of all
reissue grants in the United States. Between
2009 and 2012 IV represented anywhere
between 5% and 8% of all reissues in the
United States. By any metric, this is an
extraordinary percentage of reissues.
We determined a reissued patent to
be purchased by IV if the application date
for the reissue was before the date of
first assignment record to a company we
determined to be IV. If the assignment
to IV was before the application date, we
concluded that IV filed the reissuance. We
used the year of the application date for the
reissue as the year in which it was reissued
by IV. This allows insight into IVs post-
purchase strategy without the data being
skewed by possible delays at the USPTO.
IVs litigation
Although IVs monetisation portfolio does
not tell us who the company has been
contacting to take licences, we can see with
whom it has been litigating. IV states that
it does not enter into litigation lightly and
only after terms cannot be reached with the
other party (see www.intellectualventures.
com/insights/tag/litigation/). We looked
at all the US patents in IIF to determine
that IV had either filed, or the patent been

Figure 20. Litigated patents - assignment date to litigation filing date (years)
history for IV, we started with the US
patents in IIF and searched for cases in
the Lex Machina database for litigation
involving these patents. The litigation filing
dates were then compared to our calculated
date of assignment to IV. IV filed cases
were then split into those in which IV was
a named party in the case and those in
which a holding company was named. For
any holding company, we also did a manual
review of the cases to ensure that the case
actually involved IV. Through the manual
review, we saw three instances of patent
assets that were assigned to IV, then sold to
another company, asserted by that company
and then sold back to IV.
Practices and preferences
IVs release of its, to date, private patent
portfolio provides important insight into
how it has deployed $5.5 billion to buy and
develop patents.
The concentration of sellers in IVs
portfolio struck us as significant because
some of that risk could have been avoided
by long-term planning. A few dozen
companies represented a large portion
of IVs portfolio many of those were
struggling or bankrupt. Combining cross-
licensing and springing licences could have
reduced the long-term NPE risk.
IVs post-acquisition patent
development practices also suggest that
companies should consider increased use
of continuation and reissue practices as
tools to obtain patents with claims having
interesting scope.
The public list also gives companies
an opportunity to better assess their
exposure and risk from IVs portfolio. The
standardised taxonomy can be analysed
against the companys revenue sources and
the IV portfolio expiration dates to assess
the companys exposure over time and by

a companys negotiations with IV.
The data reveals some of IVs important
practices and preferences. From preferred
buying criteria to post-purchase patent
development to substantially increased
litigation, the data allows us to ask and
answer many questions, and we have had
a chance to present only a portion of our
analysis in this article. Areas for future
discussion include what is inside the ISF and
IDF portfolios, deeper international analysis
and deeper analysis of technology fields.

The publication of IVs patent assets allows
companies to take a number of steps in
terms of avoiding disputes with the firm and
leveraging the services it offers, including
the following:
Reducing future NPE risks enter into
cross-licences or licences that spring
when a transfer to an NPE occurs. Look
both within your space and in adjacent
and complementary market spaces.
Consider using springing licences
that focus on NPE risk (eg, licence on
transfer) as well. Defensive aggregators
such as AST, OIN, RPX and Unified
Patents can also help to reduce risk.
Patent buying refine the buying
programme criteria to favour patents
between eight and 12 years from
the priority date and also favour the
availability of open continuations.
Post-acquisition, implement a patent
development plan for acquired assets.
Patent portfolio development consider
increasing continuation practice (and
reissues) to a more substantial portion
of your portfolio (eg, more than 5%).
Analyse IV exposure determine what
your initial exposure to IV looks like
and find out when that portion of the
portfolio expires.
