US Patent Trolls Are Leaving and the Eastern District of Texas Sees Patent Cases Falling by More Than Half

Posted in America, Courtroom, Patents at 10:14 am by Dr. Roy Schestowitz

Summary: The decline of patent aggression in the US and the patent microcosm’s response to Justices, having ruled in TC Heartland, curtailing patent trolls

THE world is changing for the better when it comes to patents. Sure, the European Patent Office (EPO) is in trouble as patent scope is out of control there, but in the US things are improving. The EPO‘s friends at IP Europe wrote/quoted: “Development of innovative new standards jeopardised by #IEEE patent policy”

We wrote about IEEE the other day, specifically in relation to this article. This is a lie. IP Europe knows that it’s a lie. But it’s paid to lobby for patent extremists such as Microsoft. The IEEE is US-based and it’s possibly leaning towards liberal policies. That may mean no patent tax on standards.

In various other ways the US improving. Patent trolls seem to be on their way out. We have not heard of Erich Spangenberg for a while (he nearly disappeared). He is one of the most disgusting patent trolls of all. He had blackmailed over a thousand (maybe thousands) of firms using what later turned out to be an invalid patent and now, according to IAM, he is “back buying in the US”. To quote:

IPNav founder and renowned [sic] patent monetiser [sic] Erich Spangenberg is back buying US assets. According to an 18th September notice on the USPTO patent assignment database an entity called Page Innovations LLC acquired a single patent from inventor Justin Page relating to identity theft protection. In the assignment cover sheet Spangenberg is listed as the manager of Page Innovations. The details of the assignment were first reported in an RPX weekly email.

We have been writing about RPX for nearly a decade. We’ll come back to RPX in a moment.

The biggest news on the patent front was reported by Joe Mullin several days ago. It’s extremely pleasing to see that the US Supreme Court has managed to eject many patent trolls out of Texas. Here are some numbers:

New lawsuits are down—way down—in the mostly rural district that was once the national hotspot for patent disputes.

For several years, the Eastern District of Texas hosted more patent lawsuits than any other judicial district in the country. Last year, East Texas saw more patent lawsuits filed than the next four judicial districts combined. But in May, the Supreme Court sharply limited where patent owners can choose to file their lawsuits, in a case called TC Heartland. That’s leading to a sharp change in the geography of patent litigation.


The trend seems likely to continue, given a recent case called In re: Cray Inc., in which an appeals court clarified how TC Heartland must be applied. In that case, a federal judge ruled that a case against supercomputer manufacturer Cray could be kept in East Texas because the company employed a single work-from-home employee in the district. The top patent appeals court sharply disagreed, though, and overturned that decision, forcing the Cray case out of East Texas.

“The patterns we’re seeing are changing dramatically, and the double-digit dominance of East Texas is gone,” said Brian Howard, Lex Machina’s data scientist, in an interview with Ars.

United for Patent Reform‏ said: “Since #TCHeartland #patenttroll filings in #EDTX have dropped from 50% to 26%…”

This is based on Lex Machina.

Here is RPX’s take on some of the latest figures: “Patent law faces continued uncertainty in all three branches of government. The Supreme Court’s TC Heartland decision in May likely precipitated a dip in new patent litigation that carried unevenly through the third quarter. While litigation remains slow overall, plaintiffs have begun to test the bounds of TC Heartland by bringing novel venue arguments in the Eastern District of Texas and by charting new courses in Delaware, California, and Illinois. On the other hand, the tables could turn: the Court granted certiorari in Oil States in June, casting the continued existence of inter partes review (IPR) into doubt. Though most commentators discount petitioner Oil States’s likelihood of success, even the slightest potential for victory is a ray of hope for patent owners.”

On the Federal Circuit reaffirming all this, here is another belated take (we wrote about this before):

Until the U.S. Supreme Court’s May 22, 2017 ruling in TC Heartland v. Kraft Foods, the Court of Appeals for the Federal Circuit and the United States district courts had interpreted the patent venue statute, 28 U.S.C. §1400(b), to allow plaintiffs to bring a patent infringement case against a domestic corporation in any district court where there is personal jurisdiction over that corporate defendant. The Supreme Court’s TC Heartland ruling, however, clarified that personal jurisdiction alone does not convey venue for patent cases under the patent venue statute. But that clarification led to confusion as to how to interpret the venue statute itself. The Federal Circuit just addressed that confusion in In re Cray Inc.

In re Cray was also an important decision because it helped highlight the sheer disregard for the law (and the Supreme Court) down in Texas. It is hopefully a lot clearer now (to more trolls) that there’s nothing attractive about Texas. The figures speak for themselves.

What Else is New

  1. Aggressive New Activities of Microsoft-Connected Patent Trolls: Finjan, Intellectual Ventures, and Dominion Harbor

    The extensive group of Microsoft-connected patent trolls is still very much active; Microsoft funds them, arms them, and gives them instructions while offering people 'protection' from them (if and only if they choose Azure)

  2. Battistelli's Ongoing Attacks on the Boards Are Helping Unitary Patent (UPC), Which in Turn Helps French Patent Trolls

    Battistelli will likely be remembered not only as the man who attacked justice (and judges) but also rendered staff redundant, issued a lot of highly controversial patents, and by doing so helped the insurgence of patent trolls in Europe

    Links for the day

  4. SUEPO: “Today May Be Your Last Chance to Demonstrate Against the Seriously Flawed Reforms That Mr Battistelli Has Imposed” on EPO Staff

    Benoît Battistelli will likely remain involved in EPO affairs for a long time to come (even through a fellow Frenchman, Campinos, whom he swaps two chairs with at the Office and CEIPI), but today is the last opportunity for EPO staff to march in protest against the Battistelli regime, which for the first time ever will result in major staff cuts and growing irrelevance for the Office

  6. BIO, MDMA and PhRMA Are Pushing the PTAB-Hostile STRONGER Patents Act While IAM and Patently-O Continue to Bash PTAB

    The patent microcosm, which compares the Board to the above (crude analogy from Judge Rader and other patent extremists), is still trying to kill inter partes reviews (IPRs), in effect overlooking its own hypocrisy on the matter (they don’t want patent justice, they just want to metaphorically ‘shoot down’ the judges)

  7. 35 U.S.C. § 101 is Still Effectively Tackling Software Patents in the US, But Patent Law Firms Lie/Distort to 'Sell' These Anyway

    The assertion that software patents are still worth pursuing in 2018 is based on carefully-constructed spin which mis-frames several court decisions and underplays/downplays/ignores pretty much everything that does not suit the narrative

  8. Battistelli's EPO Became Extremely Reliant on China for Distraction and on Endless Supply of Applications (Supply Which Doesn't Exist)

    Discussion about the EPO granting machine (or patent-printing machine) and figures the way EPO management would rather the public won't ever see them; the concept that China means redemption for this patent system is as laughable as always

  9. The US International Trade Commission (USITC) Against Comcast, Courtesy of the Intellectual Ventures-Connected Rovi

    The USITC/ITC, which mostly serves to impose embargoes (sometimes in shocking defiance of PTAB decisions), is being invoked by a firm connected to the world’s largest patent troll, Intellectual Ventures

  12. From PTAB Bashing to Federal Circuit (CAFC) Bashing: How the Patent 'Industry' Sells Software Patents

    The latest tactics of the patent microcosm are just about as distasteful as last month's (or last year's), with focus shifting to the courts and few broadly-misinterpreted patent cases (mainly Finjan, Berkheimer, and Aatrix)

  13. Patent Maximalists Keep Coming Up With New Terms and Buzzwords to Bypass the Practical Ban on Software Patents

    The fightback against Section 101 and the US Supreme Court (notably Alice) seems to concentrate on old and new buzzwords, such as "Software as a Medical Device" ("SaMD") or "Fourth Industrial Revolution" ("4IR"), which the EPO recently paid European media to spread and promote

  14. News About Patents is Often Just Advertisements Composed Directly or Indirectly by Companies That Sell Patents and Patent Services

    Infomercials are still dominant among news about patents, in effect drowning out the signal (real journalism) and instead pushing agenda that is detached from reality, pertinent facts, objective assessment, public interest and so on

  15. Blocks and Paywalls Won't Protect the Patent Trolls' Lobby From Scrutiny/Fact-Checking

    Joff Wild and Benoît Battistelli have much in common, including patent maximalism and chronic resistance to facts (or fact-checking)

  16. China Has Become Very Aggressive With Patents

    China now targets other Asian countries/firms -- more so than Western firms -- with patent lawsuits; we expect this to get worse in years to come

  17. UPC/Battistelli Booster IAM Blames Brexit Rather Than EPO Abuses

    While the EPO is collapsing due to mismanagement the boosters of Team Battistelli would rather deflect and speak about Brexit, which is itself partly motivated by such mismanagement

    Rina Ronja Kari is the latest MEP attempting to compel the Commission to actually do something about the EPO other than turning a blind eye

  20. TXED Courts Are Causing Businesses to Leave the District, Notably For Fear That Having Any Operations Based There is a Legal Liability

    A discussion about the infamous abundance of patent cases in the Eastern District of Texas (TXED/EDTX) and what this will mean for businesses that have branches or any form of operations there (making them subjected to lawsuits in that district even after TC Heartland)

  21. PTAB Hatred is So Intense Among the Patent 'Industry' That Even Scammers Are Hailed as Champions If They Target PTAB

    The patent microcosm is so eager to stop the Patent Trial and Appeal Board (PTAB) that it's supporting sham deals (or "scams") and exploits/distorts the voice of the new USPTO Director to come up with PTAB-hostile catchphrases

  22. The Patent 'Industry' is Increasingly Mocking CAFC and Its Judges Because It Doesn't Like the Decisions

    Judgmental patent maximalists are still respecting high courts only when it suits them; whenever the outcome is not desirable they're willing to attack the legitimacy of the courts and the competence of judges, even resorting to racist ad hominem attacks if necessary

  23. The Patent Trial and Appeal Board (PTAB) Carries on Enforcing § 101, Invalidating Software Patents and Upsetting the Patent 'Industry' in the Process

    A quick report on where PTAB stands at the moment, some time ahead of the Oil States decision (soon to come from the US Supreme Court)

  24. Luxembourg Can Become a Hub of Patent Trolls If the EPO Carries on With Its 'Reforms', Even Without the UPC

    With or without the Unified Patent Court (UPC), which is the wet dream of patent trolls and their legal representatives, the EPO's terrible policies have landed a lot of low-quality patents on the hands of patent trolls (many of which operate through city-states that exist for tax evasion -- a fiscal environment ripe for shells)

  25. The Patent 'Printing Machine' of the EPO Will Spawn Many Lawsuits and Extortions (Threats of Lawsuits), in Effect Taxing Europe

    The money-obsessed, money-printing patent office, where the assembly line mentality has been adopted and patent-printing management is in charge, is devaluing or diluting the pool of European Patents, more so with restrictions (monetary barriers) to challenging bad patents

  27. Deleted EPO Tweets and Promotion of Software Patents Amid Complaints About Abuse and Demise of Patent Quality

    Another ordinary day at the EPO with repressions of workforce, promotion of patents that aren't even allowed, and Team UPC failing to get its act together

  28. Guest Post: Suspected “Whitewashing” Operations by Željko Topić in Croatia

    Articles about EPO Vice-President Željko Topić are disappearing and sources indicate that it’s a result of yet more SLAPP from him

  29. Monumental Effort to Highlight Decline in Quality of European Patents (a Quarter of Examiners Sign Petition in Spite of Fear), Yet Barely Any Press Coverage

    he media in Europe continues to be largely apathetic towards the EPO crisis, instead relaying a bunch of press releases and doctored figures from the EPO; only blogs that closely follow EPO scandals bothered mentioning the new petition

  30. Careful Not to Conflate UPC Critics With AfD or Anti-EU Elements

    The tyrannical Unified Patent Court (UPC) is being spun as something that only fascists would oppose after the right-wing, anti-EU politicians in Germany express strong opposition to it
