Patent Trolls Show Immunity to Antitrust: Patent Trolls Unscathed by Antitrust Claims from Tech-Sector Companies

Patent trolls have become a prominent force to be reckoned with for tech-sector companies in the United States, and tech-sector companies’ recent failure in using antitrust law to combat patent trolls indicates a continuation of that prominence.

Patent trolls have been quite the thorn in the side of tech-sector companies. The term “patent troll” is the pejorative pop culture title for the group of firms also known as non-practicing entities, patent assertion entities, and patent holding companies. These entities buy patents, not with the purpose of utilizing the patent’s technology, but with the purpose of suing companies for patent infringement. Patent trolls have made up around 85% of patent litigation against tech-sector companies in 2018. Moreover, in comparison to the first four months of 2018, the first four months of 2020 saw a 30% increase in patent litigation from patent trolls.

At a high-level, antitrust law appears to be a proper tool for wrangling patent trolls. Antitrust law cracks down on anticompetitive agreements and monopolies for the sake of promoting consumer welfare. Patents are effectively legal monopolies over a claimed invention, and patent trolls use these legal monopolies to instigate frivolous patent infringement lawsuits on companies. Such lawsuits increase litigation and licensing costs for companies who can then push such costs, via increased product prices, onto the downstream consumer.

In an attempt to go on the offensive, tech-sector companies have brought antitrust claims against patent trolls. The antitrust claims have operated on one of two theories. In Intellectual Ventures I LLC v. Capital One from 2017, Capital One counterclaimed antitrust remedies on the basis of a patent troll suing Capital One for patent infringement. More recently, Intel Corp. v. Fortress Investment Group LLC from 2021 entailed a motion to dismiss on Intel’s antitrust claims based on a patent troll’s accumulation of patents. Both attempts have been thoroughly crushed in the district courts.

As indicated by Capital One, the action by patent trolls of suing for patent infringement appears to be well-shielded by Noerr-Pennington immunity. Noerr-Pennington immunity is immunity from antitrust claims for petitioning a government body. Suing a company for patent infringement is petitioning the judiciary and, therefore, falls under Noerr-Pennington immunity. However, lawsuits can be stripped of Noerr-Pennington immunity if the lawsuit constitutes sham litigation. Sham litigation entails litigation where no reasonable litigant could expect success on the merits and has the subjective intent to directly interfere with a competitor’s business relationships. Capital One suggests that the most baseless lawsuits by patent trolls with the sole purpose of reaching a quick settlement are still unlikely to be sham litigation. The opinion reiterated that the subjective prong requires the sued party to be a competitor, and patent trolls, who do not produce any products or services, are unlikely to be a competitor to sued companies who do produce products and services.

As indicated by the dismissal of the antitrust claims at the pleading stage in Intel, an antitrust claim against the accumulation of patents by a patent troll has some inherent, potentially insurmountable, difficulties. Antitrust liability requires showing a relevant market followed by market power and a tendency towards anticompetitive effects or followed by direct evidence of anticompetitive effects. First, relevant markets for patents tend to be too broad, and broad relevant markets reduce the probability that a single entity wields enough market power to have an anticompetitive effect. With patent trolls, the relevant markets include the patent troll’s patents and any patents or technologies that are reasonably interchangeable with the patent troll’s patents. The set of reasonably interchangeable technologies is rather amorphous and large, given the multitude of ways in any area of technology to perform the same task and the total number of patents having surpassed ten million. Some of the relevant markets in Intel, such as “mobile device-to-device communication” and “device authorization,” were so broad as to make anticompetitive effects by the patent troll implausible. Second, even with a narrower market, a patent troll is unlikely to have market power. As suggested in Intel, the total set of patents and technology in the narrower market is likely far larger than the couple of patents being asserted by the patent troll. Third, evidence demonstrating that a patent troll creates anticompetitive effects is few and far between. Showing anticompetitive effects likely requires a combination of increased, supracompetitive prices and a drop in product output or quality. Showing that a patent troll creates a supracompetitive licensing price over a patent is difficult. As in Intel, the few licensing agreements for a patent troll’s patent are likely settlements from a patent troll’s previous assertions which are hidden by confidentiality.

These recent decisions are only district court decisions. However, Capital One provides a strong, clear-cut view on Noerr-Pennington immunity for patent infringement suits by patent trolls, and Intel found that the antitrust claims against the accumulation of patents could not pass the low bar of plausibility in the pleading stage. With patent trolls’ exclusive existence in the instigation of patent infringement lawsuits and the accumulation of patents, the recent decisions appear to significantly reduce the usefulness of antitrust law against the toll-taking patent trolls.
