A Modality for Defining Patent Monetization Companies

Nicole Shanahan

Patent monetization companies are largely to blame for the inefficiencies in the patent marketplace today.  Many scholars, academics, and private research institutions have attempted to understand just how bad things have gotten, and that research has received deserved attention from the government, including President Obama who has been vocal on patent law reform.[1]  However, one of the largest problems with the patent reform discussion is the difficulty with terminology related to the business activities of patent monetization companies.  What still is not well understood from the depths of data explaining the fiscal impacts of our patent system is a comprehensive modality for precisely detailing the business model a patent monetization entity utilizes.  To adequately define and categorize these entities’ impact by their practices, a granular understanding of their behavior is necessary.

In an expanded paper entitled “Deconstructing the Patent Bubble: An Exploration of Patent Monetization Entities from Sewing Machine Combination to Rockstar Bidco,” I survey the history of commercial patent monetization since the first large-scale patent consortium formed in the1850s.[2]  In doing so, it became clear that there is a traceable evolution of patent revenue generating techniques.  Figure 1 below shows this progression, and the remaining portion of this article explains how these various business models operate with specific examples of each.  Noticeably, the new patent monetization entities have chosen from the ranks of prior models to create flexible, hybrid entities.[3]  By virtue of their immense diversity and numbers, these entities will be challenging and labor intensive to analyze under the proposed Saving High-Tech Innovators from Egregious Legal Disputes Act (SHIELD Act) and other legislative reform requiring courts to issue legal proceedings based on entity type.[4]

Evolution of Patent Monetization


1. Patent Consortium Model

Over a hundred years before the world came to know the term “patent troll,” the first strategic patent pool was formed to cover sewing machine technology.[5]  Patent pools, also known as consortiums, are among the oldest and longest surviving aggregation business models that continue to flourish today.  They are formed via an agreement between several companies who pay fees to aggregate and share licenses to valuable patents containing overlapping claims.  Sewing Machine Combination was the first known patent consortium that participating members leveraged as a means to overtake non-member competitors.[6]  Operating during a period known as the “sewing machine wars” between 1856 and 1877, when its last patent expired, Sewing Machine Combination provides an important historical example of how patent owners can escape commercial gridlock, and unleash productivity and innovation via cross-licensing agreements.[7]

While Sewing Machine Combination made it possible for the sewing machine manufacturers to start making and selling sewing machines, rather than working full-time on suing each other out of existence, it has yet to be seen whether modern consortiums provide the same level of innovation.[8]  In the smartphone industry, such attempts at efficient consortiums have just recently started to ramp up, but despite the existence of a few large smartphone consortiums, the rate of smartphone litigation continues to rise.[9]  The aftermath of the sale of Nortel Networks’ patent portfolio to Rockstar Bidco exemplifies how smartphone consortiums have served to create competitive patent thickets, known popularly as the “Smartphone Wars.”[10]  Current trends support the conclusion that the consortiums are serving valuable strategic purposes that help smartphone companies enter and compete in the marketplace through patent partnerships.[11]

If done correctly, the pro-competitive benefits of a successful smartphone consortium will outweigh any anticompetitive effects by promoting healthy industry competition, while still upholding licensing commitments such as those required under standards setting organizations.[12]  For example, Google’s adversarial relationship with the Rockstar Bidco consortium (consisting of Apple, Microsoft, RIM, Sony, Ericsson, and EMC) presents a unique opportunity to re-assess the treatment of standard-essential patents existing within competitive patent thickets.[13]

2. Lemelson NPE Model

While Non-Practicing Entity (NPE) patent litigation has been around for over 150 years, the first corporate-level patent monetization operation originated from Jerome Lemelson in the 1960s.[14]  This famed inventor described having patented “anything that came to mind,” and incorporated the Licensing Management Corporation in order to bring to market patents under his name as well as other independent inventors.[15]  Lemselon was the first person to use patent development as a business model, by hiring in the place of engineers and business people, an “army of patent attorneys” dedicated to drafting and prosecuting patent applications.[16]  He was one of the first to make use of contingency fee litigators and by the 1980s inspired several others to adopt the same business model.[17]

Among the most notable “Lemelson patent development companies” today are Rambus and Tessera.[18]  While Rambus generally receives less criticism from hardline NPE critics compared to other patent assertion entities because of their relatively high focus on research, Rambus has been involved in its fair share of controversy.[19]  Founded in 1990 as a chip developer by two inventor-professors, Rambus started as a licensing company that provided, in addition to patent licenses, the services of engineers to assist chip companies in their development of Dynamic Random-Access Memory (DRAM) technology.[20]

There are several companies that started as operating companies (in the business of making and selling actual products) but due to financial contraints or strategic purposes, opted for a strictly Lemelson approach.[21]  The largest of these entities is Tessera, who started as a manufacturer of semiconductor packaging.[22]  Today, Tessera no longer manufactures products and has been actively asserting patents not just in the federal courts, but also at the U.S. International Trade Commission (ITC).[23]  Tessera’s use of the ITC as a forum to pressure companies into paying licensing fees exemplifies how patent monetization companies have leveraged the ITC’s arguably lower standard for issuing injuctions.[24]

3. Acquire & Assert Model

The patent marketplace developments in the late 1980s to early 1990s were probably the most significant in terms of bolstering the NPE model.  Models built entirely on patent acquisitions and the transactions created by brokerages and auction houses made the patent marketplace a much more dynamic place.  The availability of entire portfolios paired with the greater availability of contingency fee litigators such as Raymond Niro (for whom the term “patent troll” was apparently first coined) meant that a patent monetizer no longer had to invest in engineers, patent attorneys, or technologist of any sort.[25]  The average cost of taking a company to court dropped dramatically and the speed at which these companies saw profits was staggering.[26]  Compared to the traditional Lemelson model that took much more time and investment, the acquisition-assertion model eliminated many of the barriers to entry of becoming a patent holding entity.[27]  Given the relative lack of transactions in the marketplace previously, these entities were able to pull from a larger pool of patent holders willing to sell their property.  These sellers included individual inventors unable to find contingency fee lawyers, failed start-up companies, or companies looking to partner with an assertion entity.[28]

Companies operating under the acquisition-assertion model are effective because of the economics surrounding patent litigation.  For example, in Texas it could cost an accused infringer more than $2.5 million to litigate a case with $1 to $25 million at stake.[29]  Discovery alone could cost as much as $1.5 million.[30]  The risks companies face when responding to infringement demands include massive litigations costs, the risk of a damages payments far greater than an early settlement payout and, worst yet, an injunction against their product.[31]  On the other hand, the patent holding company operating under the acquisition-assertion model has discovery obligations that are much smaller, oftentimes throwing together a handful of documents from the acquisition.[32]

4. Publicly Traded PMEs

Publicly traded Patent Monetization Entities (PMEs) run the gamut in terms of how they develop patent portfolios and the means by which they monetize them, but they deserve a unique category because they are subject to higher public scrutiny and generally rely on more stable patent revenue models.  There are currently seventeen PMEs listed on the public market.[33]  Another four PMEs who were once listed have since become delisted for various reasons.[34]  The group as a whole has seen high volatility on the stock market.[35]  The remaining publicly listed PMEs have lost substantial value since their IPO and have struggled to post profits for investors.[36]

After reviewing the list of companies and their past stock performance, it becomes clear that PMEs are more successful if they have many moderate sized wins versus a few large wins.  Thus, success becomes a matter of transaction volume: more portfolios mean more potential lawsuits and licensees as well as a guaranteed pipeline of royalties.  Other factors among the most successful publicly traded PMEs (such as Acacia, Interdigital, VirnetX, Universal Display, and Tessera) include: a diversity of patents covering a range of technologies, portfolios containing Standard-Essential Patents (SEPs), portfolios covering the mobile and semiconductor industries, portfolios that include patents in Europe and Asia, and regularity in launching new lawsuits.[37]  Alternatively, characteristics pertaining to struggling publicly traded PMEs include a change from an operating to non-operating model that fails to acquire new portfolios (TIVO, Document Security Systems, Wi-LAN, Opti, Inc., and Worlds, Inc.), a considerably high IPO valuation (RPX Corporation, Vringo), and attempting to go from a non-operating to operating model (Democrasoft, Asure Software).[38]  A full list of publicly traded NPEs as well as their classification is included in Table 1:

5. The Hybrid PME

What makes modern PMEs interesting is their ability to articulate, execute, and sell hybrid monetization models.  The most famous of these, receiving their fair share of attention by both the media and scholars, are Intellectual Ventures (IV) and RPX Corporation.[40]  Interestingly, two of the founders of RPX Corporation previously worked at IV and all of the founders from both firms taken together have experience in every one of the models discussed above.[41]  Intellectual Ventures was founded in 2000 by Nathan Myhrvold and Edward Jung, both of whom formerly served in high-level positions at Microsoft.[42]  RPX Corporation’s John Amster and Geoffrey Barker were both former vice-presidents at IV and worked closely with Myhrvold in developing the company’s software licensing strategy.[43]

Both companies have had huge success raising private funds to finance portfolio development and in doing so, have come to own massive portfolios in a short amount of time.[44]  While today IV practices a combination of patent development (early Lemelson Model) and acquisition (Acacia’s model), it originally attracted financial backing from the companies that are now the target of its revenue model.[45]  With $5 billion in funds and an estimated 40,000 patents and patent applications, IV is the largest NPE in the world.[46]  While RPX Corporation has a portfolio that is just a fraction of that size, it also had early success attracting venture capital funding and support from early members, the first of which was Cisco (whose former head of patents, Mallun Yen, is now RPX’s executive vice-president).[47]  RPX Corporation has spent over $700 million to acquire approximately 3800 patent assets across several industries, most notably mobile handsets.[48]

Both IV and RPX view themselves as providing essential financial services, instead of legal services—a  distinction that presents obvious implications.  Nathan Myhrvold has often called his $5 billion in investments a venture capital fund,[49] and RPX formally changed their industry sector from legal services to financial services in 2009.[50]  Some researchers have estimated that for a $5 billion dollar fund to be successful, it would take at least $40 billion in returns over a ten year period (last year IV earned just barely $2 billion in revenue).[51]  This means IV will need to engage in high yield transactions that will likely require taking many more companies to court per year.  In contrast, RPX’s business model requires it to get the lowest possible price for “high litigation risk” portfolios,[52] but since prices must remain competitive for patent owners in order for them to make a deal with RPX in the first place, their cost saving services have nothing to do with the actual deal, and more to do with replacing lawyers’ fees.

6. Conclusion

Given the various differences in the way patent monetization companies operate, the government should pay special attention to the relative value of each practice. Some models provide a greater public benefit to others, but all seem to benefit from a market environment in which nuisance-based lawsuits remain the most attractive liquidation option.
