On Wednesday, June 27th, a pair of orders of dismissal, one entered in the District of Delaware and the other entered in the Northern District of California, marked the official end of the patent war which played out between consumer tech giants Apple and Samsung for the better part of the past decade. This legal dispute, which was brought to courts in 10 different countries and even went to the U.S. Supreme Court, is notable because it undermines the argument that major patent infringement battles harm tech consumers through added costs and blocking innovation.

On appeal, WesternGeco argued 1) the Board erred as to its unpatentability determinations; and 2) the IPR proceedings were time-barred under 35 U.S.C. § 315(b) because ION acted in privity with PGS, and over a year passed between its infringement complaint against ION and the PGS IPR petition. Based on the Federal Circuit’s en banc decision known as Wi-Fi One, the time-bar issue was appealable, but WesternGeco’s argument was unpersuasive because the relationship between ION and PGS was not close enough to trigger the time bar.

On Wednesday, April 25th, the Court of Appeals for the Federal Circuit issued a precedential decision in Gilead Sciences v. Merck & Co. et. al., which affirmed a lower court’s ruling that Merck could not assert claims from two patents against Gilead because Merck had unclean hands regarding the patents. The case, coming out of the Northern District of California, involves patents covering methods for effectively treating the hepatitis C virus (HCV)… Reviewing the facts of the case, the Federal Circuit panel found sufficient evidence supporting the district court’s findings of serious business misconduct by Merck, that Merck’s misconduct was related to the litigation and that litigation misconduct had occurred based on false testimony provided by Merck’s non-firewalled patent lawyer, who had originally testified that he was not a party to the March 2004 phone call with Pharmasset.

In invalidating the Idenix patent, the Delaware district court effectively overturns what had been the largest award for royalty damages in a U.S. patent infringement case ever handed out. After a two-week trial in December 2016, the jury had awarded Index $2.64 billion in damages, which was based on finding Gilead infringed the Idenix patent – U.S. Patent No. 7,608,597 — by selling the hepatitis C virus (HCV) treatments Harvoni and Sovaldi.

On Monday, February 5th, Finnish enterprise cybersecurity solutions firm SSH Communications Security announced that it had entered into a patent cross-license and settlement agreement with Japanese electronics conglomerate Sony Corporation (NYSE:SNE). The agreement reportedly resolves all patent disputes between the two companies after Sony successfully challenged the validity of two U.S. patents owned by SSH Communications at the Patent Trial and Appeal Board (PTAB).

Supporters of the Patent Trial and Appeal Board (PTAB) continue to claim that the facts and figures showing the PTAB is overruling Article III federal district court adjudication on patent validity is fictitious. Ignoring the truth doesn’t make the truth any less correct. Still, in some circles the fiction spewed by those who champion the patent killing fields of the PTAB continues to be persuasive… More alarming, in many of the cases where the PTAB has overruled district court adjudication of the patents there were findings of willful infringement, meaning the defendants (and ulitmately the IPR petitioners) knowingly and intentionally infringed the patents adjudicated to contain valid claims. Notwithstanding, the PTAB, dutifully complied with their role as executioner of patents.

69% of cases reaching a final decision by the PTAB have all claims invalidated. 82.5% of patents reviewed by PTAB in a final decision are found defective… As the facts laid out in this article show, the PTAB is substantially more likely to find patents to be defective than a Federal District Court. This reality is a significant problem for patent owners, and should be a serious concern for anyone at all concerned with separation of powers. Even after prevailing in Federal District Court, and even after prevailing at the Federal Circuit as VirnetX had done, the PTAB can still invalidate claims already adjudicated as valid by an Article III tribunal. If patents are to be considered any kind of property right (as the statute says) title must at some point quiet, and an Article I administrative tribunal simply cannot have the power to overrule an Article III tribunal. If patent owners cannot have full faith and confidence in the patent granted by the Federal Government, and they similarly cannot have full faith and confidence in a final adjudication by the federal courts, how can they be expected to invest the millions, and sometimes billions, required to bring technology to the marketplace?

There have been 220 patents upheld as valid in real courts and also subject to a final written decision in the PTAB. The PTAB only agreed with the real courts on 52 patents, while disagreeing with them on 168 patents. If the U.S. legal system is the gold-standard, that means the PTAB is erroneously invalidating patents 76% of the time… In the PTAB, generally only two grounds of attack are available – 35 U.S.C. §102 for novelty and 35 U.S.C. §103 for non-obviousness. But in the real court four grounds are available as a defense – along with §102, §103, accused infringers are also afforded validity challenges under 35 U.S.C. §101 for basic patentability and 35 U.S.C. §112 for specification. So how is it that the PTAB invalidates three times as many patents with only half as many grounds available? The only answer is because it is specifically designed to help infringers by bypassing due process protections afforded to inventors in real courts. Apologists will go on to argue that the PTAB had better evidence, better prior art, better experts, better judges – nonsense! The real courts have rules and procedures which are tremendously more thorough, developed, proven, and fair. The PTAB has not and cannot measure up.

In a research project funded by the Austrian Science Fund (FWF), evidence emerged that a higher expression of the GIRK1 protein in malignant tissue samples was linked to higher relapse and mortality rates in breast cancer patients who have gone through surgery. The novel use of the GIRK1 protein as a biomarker could have a great impact on breast cancer diagnostics and treatments and further research could yield more discovery on the interdependence of GIRK1 with other important biological pathways critical to cancer management… Unfortunately, discovery of GIRK1 as a biomarker for breast cancer diagnostics would run into 35 U.S.C. § 101, the basic threshold statute for determining patentability of subject matter, under the Supreme Court’s March 2012 ruling in Mayo Collaborative Services v. Prometheus Laboratories, Inc. In that case, the Court held that processes involving correlations between blood test results and patient health is not patent-eligible subject matter because the process incorporates laws of nature. This would seemingly render any processes involving the application of GIRK1 as a biomarker for breast cancer prognoses unpatentable as well as the expression of GIRK1 occurs naturally.

Doubtless there are some manufacturing firms, such as Telebrands, who are great endorsers of inter partes review (IPR) proceedings at the Patent Trial and Appeal Board (PTAB) and how that agency has found in favor of copy-cats even as federal courts have repeatedly issued injunctions and found in favor of the inventor of an award winning toy (see here and here).But the manufacturing sector did not all line up in favor of Greene’s Energy Group, although most did. Nevertheless, given that manufacturing firms tend to license patents and do not necessarily develop their own technologies, it is informative to see how this sector feels that the Supreme Court should decide Oil States.

A jury verdict recently entered in a patent infringement case in the Eastern District of Texas held that plaintiff Packet Intelligence, a patent owning entity headquartered in Marshall, TX, did not prove infringement of claims from three patents asserted against Canadian communications service solutions provider Sandvine Corporation (TSE:SVC). The jury verdict comes less than one month after Packet Intelligence won a jury verdict of infringement on the same asserted patents in a different Eastern Texas case filed against Westford, MA-based application and network performance management firm NetScout Systems (NASDAQ:NTCT).

The government’s brief argues that IPR proceedings at the PTAB are consistent with Article III because, in its view, patents are public rights and not private ones and the right for an inventor to seek a patent is a public right. In the government’s eyes, it is constitutionally permissible for the U.S. Patent and Trademark Office to reassess previously issued patents for revoking in order to “correct its own errors.” If the PTAB errs, then patent owners have legal recourse in appealing those cases to the Court of Appeals for the Federal Circuit, the government argues.

On August 8th, a memorandum opinion entered in the District of Nebraska overturned a jury verdict award of more than $30 million handed to Omaha, NE-based intellectual property licensing firm Prism Technologies LLC back in June 2015. After Prism won the multi-million damages award from Overland Park, KS-based telecommunications company Sprint (NYSE:S), a decision by the Court of Appeals for the Federal Circuit upheld findings of patent invalidity in a different case involving the patents asserted by Prism. That Federal Circuit decision was applied to Prism’s case against Sprint in a way which shows patent owners that their intellectual property rights are seemingly never safe under the current U.S. patent policy regime.

Equitable estoppel may be appropriate for the defendant in SCA v. First Quality since the plaintiff was silent for years after the defendant asserted invalidity (possibly fulfilling the misleading conduct through inaction and reliance on that conduct). But can equitable estoppel be relied upon as a defense against a dormant plaintiff in the example illustrated above? Below, we consider the two elements of equitable estoppel that replace the unreasonable delay element of laches: misleading conduct and reliance.

So obviously the patent claims VirnetX has used to pursue infringers such as Apple and Microsoft are not the weak patents that opponents of the patent system claim are the scourge of the system. Well — not so fast! Just because an Article III federal district court confirms the validity of a patent doesn’t mean anything anymore. Indeed, federal courts have become subordinate to the PTAB, which is as ridiculous as it sounds but sadly true. A patent is not valid until an Article I executive tribunal says so, and absolutely no deference is paid to Article III judges of the United States federal courts.
