Some cool graphs from my paper on IP litigation in US district courts

I have just revised my article, IP Litigation in US District Courts: 1994 to 2014, which will be published in Volume 101 of the Iowa Law Review next year.  (You can download the article from ssrn now.) This post does not attempt to summarize the full article; it focuses instead on explaining some of the more interesting graphs and data visualizations in the article.

Copyright, Patent and Trademark Filings as a percentage of all IP 1994-2014

This data is presented as a 12 month moving average.

Copyright, Patent and Trademark Filings 1994—2014 (Percent)

 

Copyright, Patent and Trademark Filings (number of cases) 1994—2014

Again, this data is presented as a 12 month moving average. The difference between the dashed redline and the solid red line clearly shows the impact of lawsuits against anonymous internet file sharers.

Copyright, Patent and Trademark Filings 1994—2014 (Cases)

 

Copyright Cases 1994—2014, RIAA End-User Litigation, BitTorrent Monetization and Copyright Trolling

The impact of the current wave of copyright trolling is pretty clear.

Copyright Cases Filed in U.S. District Courts (1994—2014)

 

9 out of 10 of ‘copyright trolling’ cases are about pornography

As you can see from the table, the number of john does per suit has declined because courts have been far more skeptical of mass-joinder, but that has just led to more suits being filed.

One pornography company accounts for 80% of Copyright John Doe lawsuits filed in 2014 #CopyrightTrolling

In fact, the pornography producer, Malibu Media is such a prolific litigant that in 2014 it was the plaintiff in over 41.5% of all copyright suits nationwide. John Doe litigation is not a general response to Internet piracy; it is a niche entrepreneurial activity in and of itself.

1/2 The patent litigation explosion is not exactly as it appears, compare suits filed to #defendants.

At first glance it looks like the annual volume of patent litigation in the United States doubled in the 16 years from 1994 until 2010. In the three years from 2010 to 2013 it doubled again.

US Patent Litigation Filings, 1994–2014

 

2/2 The patent litigation explosion is not exactly as it appears, compare suits filed to #defendants.

The real trend in patent litigation over the past two decades can be seen in the number of defendants filed against. The bar chart at the bottom of the next figure shows the same filing data as in the figure above. The scatter plot in the figure below shows the estimated number of defendants. Although it appears that the number of patent cases filed exploded after 2010, looking at the estimated number of defendants, it becomes clear that the period from 2010 to 2013 was more or less a continuation of the existing trend.

Patent Cases Filed and Estimated Number of Defendants, 1994—2014

There is something wrong with the ED of Texas. Average Number of Patent Defendants per Filing 1994—2014

This figure shows the estimated number of defendants per suit for the nine most popular federal districts from 1994 to 2014 and also for an aggregation of all other districts. The vertical dashed line is set to 2011 to mark the passage of the America Invents Act. It is starkly apparent that the trend toward more defendants is greatest in the Eastern District of Texas. The estimated number of defendants in Eastern District of Texas climbs steeply from 1.66 in 1994 to 12.37 in 2010 and then drops precipitously down to 1.99 in 2014

Average Number of Patent Defendants per Filing 1994—2014

 

What does all this mean? To me, it suggests that there was not exactly a “Troll Fueled Patent Litigation Explosion” between 2010 and 2012. Once you take into account the procedural changes brought into effect in 2011 by the AIA and focus on the number of defendants rather the the number of suits it seem that there was a significant troll fueled increase in the rate of patent litigation; it is just that this increase started earlier and proceeded more smoothly than the simple case filing data suggests. I refer to this revised narrative as the Troll Fueled Patent Litigation Inflation.

District Rankings, Copyright Compared to Trademark (2010-2014)

This figure focuses your attention on the outliers, but the general story is that copyright and trademark litigation are highly correlated at a district court level.

District Rankings, Copyright Compared to Trademark (2010-2014)

Regional Variation in Patent Litigation – Evidence of Forum Selling

The popularity of the Eastern District of Texas as a forum for patent litigation is a well-known phenomenon. However, the data and analysis presented in this study provides a new way of looking at the astonishing ascendancy of this district and the problem of form shopping in patent law more generally. The extent of forum shopping in patent law can be seen by comparing the geographic distribution of patent litigation to that of copyright and trademark. This figure illustrates District rank in terms of patent versus a combined copyright and trademark ranking for cases filed between 2010 and 2014.

District Rank in terms of Patent versus Copyright and Trademark Combined (2010-2014)

District Court Ranks for Patent Litigation 1994-2014

This is crazy!

My paper explains how we got here and summarizes the excellent work of Jonas Anderson in a new paper titled ‘Court Competition for Patent Cases, and Daniel Klerman and Greg Reilly in ‘Forum Selling’ each of which go into even more detail.

District Court Ranks for Patent Litigation 1994-2014

 

The first thing to note about this figure is that, but for the Eastern District of Texas and Delaware, the geographic distribution of patent litigation over the past two decades would look remarkably stable. For most of this period, the Central District of California was the most important venue for patent litigation over the last 21 years, followed by the Northern District of California. The Northern District of Illinois has also ranked consistently somewhere between second and sixth over the same period. This relative stability contrasts markedly with the steady gains made by Delaware and the remarkable ascendancy of the Eastern District of Texas between 1994 and 2014. Notice that, were it not for the Eastern District of Texas, the scale on Figure 11 would range from 10 to 1, rather than 50 to 1. Framed accordingly, the steady ascent of Delaware from 9th in 1994 to 2nd from 2011 to the present day would be more noteworthy. However, the rise of the Eastern District of Texas from literal obscurity—it only saw 8 patent cases in 1994—to preeminence over the same period dwarfs all other changes.

Cited in Kimble v. Marvel supreme court brief re patent misuse

Someone told me that I was cited in the respondent’s brief to the Supreme Court in Kimble v. Marvel Enterprises, Inc.

Indeed, patent-license negotiations may often fail to approximate the conditions presumed by the classical economic model of efficient bargaining. See, e.g., Sag & Rohde, Patent Reform and Differential Impact, 8 Minn. J.L. Sci. & Tech. 1, 36-37 (2007) (patent holder may have asymmetrically better information about the scope and validity of the patent) ~ Kimble v. Marvel Enterprises, Inc., 2015 WL 881759 (U.S.), 45 (U.S.,2015)

In Brulotte v. Thys Co. the Supreme Court ruled that, when patents are sold in return for a royalty payment, the purchaser was not obligated to continue these payments beyond the expiration date of the patents because doing so would over-compensate the seller of the patent and improperly extend the patent monopoly beyond the intended time limit.

In other words, it is patent misuse to try to extract  royalties for use of the patent post-term. That rule is now being challenged. For a summary of the issue in the case, see http://www.oyez.org/cases/2010-2019/2014/2014_13_720

Is IP property? An outline of the debate.

Is IP Property?

The debate about whether intellectual property is really property tends to proceed along the following lines.

Pro-property advocates observe that as a matter of definition exclusive and tradable rights should be thought of as property.

Anti-property advocates note that IP rights are limited in scope and duration and subject to a number of important public interest caveats.

Pro-property advocates respond with fascinating descriptions of the law relating to nuisance, easements, riparian rights and ancient Roman laws which hold the oceans and navigable waterways in public trust to show that, for every conceivable feature of IP rights that supposedly distinguishes them from property, there is in fact a property law antecedent.

Anti-property advocates respond by saying “but that is not what you mean when you say IP is property. You mean control that is absolute, unyielding and perpetual.”

Both sides then declare victory in the debate and revert to their initial positions.

Do not upgrade to Yosemite.

I am that burning feeling of rage as the computer freezes, then restarts with the last 15 minutes of beautifully crafted prose about the definition the the Transmit clause under the Copyright Act lost forever.

I switched to a Mac to avoid this feeling.

Updated Copyright Trolling and Pornography Data for 2014

 

Copyright Lawsuits Filed in U.S. Federal Courts 2001 – 2014

Figure8

This graphs is from my forthcoming article, Copyright Trolling, An Empirical Study. The graph illustrates the effect of two separate waves of John Doe litigation. The first wave was the recording industry’s battle with filesharing technology from 2004 through 2008. The second wave began in 2010 and continues through to the present and is dominated to a remarkable degree by lawsuits relating to pornography.

There is an article in the New Yorker Online today about this phenomenon with a a closeup view of one the major plaintiffs, Malibu Media, see THE BIGGEST FILER OF COPYRIGHT LAWSUITS? THIS EROTICA WEB SITE, BY GABE FRIEDMAN . Well worth a read.

 

Patent troll statistics, a correction

In a post on Friday I mentioned that in 2012, businesses and individuals targeted by patent aggregators and patent holding companies accounted for fifty-six percent of all patent defendants. That number should actually be 37.8% of all patent defendants. 

There are estimates of even higher numbers, see Colleen Chien, Patent Trolls by the Numbers reporting RPX’s estimate that  PAEs initiated 62% of all patent litigation suits in 2012. However, it is not exactly clear how RPX determines who is and is not a patent troll. Also RPX is in the business of providing “patent risk management services”, so it is not exactly a disinterested bystander in the patent troll debate.

Christopher A. Cotropia, Jay P. Kesan & David L. Schwartz, Unpacking Patent Assertion Entities (PAEs) have provided some great data on this issue – but it still needs to be read carefully to understand what it means.

Figure 3 of that paper reports patent litigation numbers in terms of the number of individual defendants sued.

On this metric:

  • suits by large aggregators and patent holding companies increased from 31.6% of all patent litigation in 2010 to 37.8% in 2012;
  • in contrast suits by operating companies went down from 48.9% in 2010 to 47.3% in 2012;
  • if you include the IP holding companies of operating companies, suits by operating companies went down from 51.0% in 2010 to 47.8% in 2012;

Cotropia, Kesan & Schwartz round out this picture by reporting the numbers for universities & colleges, individuals & family trusts, failed operating companies & failed start-ups, and technology development companies. Some of these suits may be troll litigation, but without case specific information it is hard to tell.

 

Garcia v. Google amicus briefs with very brief summaries

Due to the level of interest in Garcia v. Google, the Ninth Circuit has a dedicated page providing information and key court documents to the public.

I have listed the Amicus briefs along with very cursory descriptions below. The briefs are all quite short.

Internet Law Professors — addressing the implications of the Court’s decision for Section 230 of the Communications Decency Act.  Section 230 is vital to the health of e-commerce and web 2.0 businesses, it provides the legal foundation for many of the most popular websites that enable users to communicate with each other or the world at large.  The panel’s broad interpretation of copyright law undermines Section 230 immunity without even expressly considering it. * I am one of the Amici for this brief.

Professors of Intellectual Property Law — arguing that the Court’s opinion misinterprets the baseline requirements for copyrightability. ** This is the brief to read for students of copyright law.

Adobe Systems, et al. It is not surprising that eBay, Facebook, Gawker, Kickstarter, Pinterest, Tumblr, Twitter, and Yahoo!  would feel strongly about this case. These amici argue that the Court’s decision and order places too much responsibility on service providers to monitor their services and denies the public’s interest in free expression and access to information. They also argue that the Court’s order is unworkable and that the ruling poses a serious threat to online service providers’ businesses.

Netflix, Inc. — arguing that that the ruling creates a new species of copyright and risks wreaking havoc with established copyright and business rules on which third party distributors, such as Netflix, depend.

International Documentary Ass’n — arguing that the Court’s opinion has created uncertainty as to several fundamental concepts that are essential to modern filmmaking.

Floor64 (publisher of Techdirt.com) & Organization for Transformative Works —arguing that the Court’s decision undermines Congress’s goal of fostering online speech by effectively stripping intermediaries of the statutory protection they depend on to deliver it — i.e. the safe harbors created by the § 230 of the Communications Decency Act and the Digital Millennium Copyright Act (17 U.S.C. § 512).)

California Broadcasters — arguing that a finding that individual performances within films and television programs may be entitled to copyright protection creates uncertainly for entertainment media creators and distributors.

News Organizations — arguing that the Court’s decision did not properly consider important First Amendment interests and that it poses serious risk to news organizations that extend far beyond the unique facts of the case at hand.

Electronic Frontier Foundation, et al. — framing the issues in Constitutional terms and addressing the standard for preliminary injunctions.

Public Citizen Litigation Group — focusing on the correct standard for issuing an injunction restraining speech.
