Bad Patents, Patent Trolls, and the PR Campaign Created to Excuse Infringement

Created using ChatGPT.

There’s a curious double standard in the way we talk about intellectual property (IP) in America.

When someone copies a copyrighted work without permission, we recognize that the creator has rights. Copyright infringement can even carry criminal penalties. When someone steals another person’s property, we call it theft, and criminal penalties can follow. But when a company uses someone else’s patented invention without permission, the patent owner who tries to stop it is often portrayed as the villain.

The strategy is remarkably simple. When a patent owner asserts its rights, attack the patent. If that isn’t enough, attack the owner. Call the patent “bad,” call its owner a “troll,” and portray any effort to enforce it as an abuse of the legal system. Even a Patent Trial and Appeal Board (PTAB) decision canceling a patent claim becomes ammunition in a broader campaign to suggest that the patent never deserved protection in the first place.

It’s all very convenient. Instead of asking whether someone has infringed a valid patent, we are encouraged to question whether the patent owner deserves protection. The strategy is to blame the victim, discredit the property right, and excuse the conduct of the party accused of violating it.

This campaign has been remarkably effective in shaping the national debate over patents. Its influence extends beyond public opinion and legislation to the institutions and judges responsible for administering patent law.

I’ve spent almost 12 years working inside the U.S. Patent and Trademark Office (USPTO), including serving as Acting Director, and have seen firsthand the care, expertise, and judgment that go into examining patent applications and administering our patent system. I’ve also seen how easily the complexity of patent law gets reduced to political slogans that bear little resemblance to how the system actually works. That experience has convinced me that the campaign against so-called bad patents and patent trolls isn’t just misleading. It is intentionally undermining confidence in the very property rights our patent system was created to protect.

False Narrative #1: America Has a Problem With “Bad Patents.”

We hear a lot about so-called bad patents. The argument usually goes something like this: The USPTO issues too many patents that never should have been granted, and those patents impose enormous costs on businesses and consumers.

Of course, patents must satisfy the requirements established by Congress. Inventions must be new, useful, and nonobvious, and patent applications must satisfy other statutory requirements. But that’s not necessarily what critics mean when they talk about “bad patents.”

Too often, a bad patent is simply one that someone would prefer not to respect. A patent becomes “bad” because it covers technology a large company wants to use without paying for it. Or because the patent owner seeks damages. Or because the patent owner doesn’t manufacture a competing product. Or because defending an infringement lawsuit is expensive.

None of those things makes a patent invalid.

A patent is a property right granted in exchange for disclosing an invention to the public. The inventor must explain the invention in sufficient detail to satisfy the law, and in return receives a limited period of exclusive rights. That bargain has helped make America the world’s leading innovation economy.

Congress recognized the importance of protecting issued patents. Under Section 282 of the Patent Act, a patent is presumed valid. In federal district court, invalidity must be established by clear and convincing evidence. That doesn’t mean every patent is valid. It means the government has already examined the invention, determined that it meets the statutory requirements, and issued a property right that should not be casually taken away.

We should ask who benefits when patents are routinely characterized as defective. It certainly isn’t the independent inventor whose patent is their most valuable asset, the startup trying to attract investors, or the university seeking to license a breakthrough discovery.

The beneficiaries are the companies with the financial resources to use patented technologies, defend infringement lawsuits, and outlast smaller patent owners. For a large company, years of litigation are a manageable business expense. For an independent inventor, the same litigation consumes the value of the invention and threatens their financial future.

Calling the patent “bad” doesn’t resolve that imbalance. It helps perpetuate it.

False Narrative #2: PTAB Challenges Prove That the Patent Office Issues Bad Patents.

Critics point to patent claims canceled by the PTAB as proof that the USPTO issues too many bad patents. But that ignores how the PTAB works.

Congress created a system in which issued patent claims can be canceled under legal standards that are far less protective of patent owners than those applied in federal district court.

First, the threshold for instituting an inter partes review is relatively low: a reasonable likelihood that the challenger will prevail on at least one challenged claim.

Second, the burden of proving unpatentability is only a preponderance of the evidence—essentially, more likely than not. In district court, invalidity must be established by clear and convincing evidence.

Third, on appeal, the U.S. Court of Appeals for the Federal Circuit reviews the PTAB’s factual findings under the highly deferential substantial-evidence standard, although legal conclusions are reviewed independently.

The consequences are significant. A patent claim can be canceled at the PTAB even though the same evidence would not have been sufficient to invalidate it in district court. And that cancellation can be affirmed on appeal even when the evidence supports a different factual conclusion.

A PTAB cancellation does not prove that the USPTO issued a bad patent. It establishes that the challenged claims failed under a different, far less demanding evidentiary standard.

We should stop treating PTAB cancellation statistics as proof of a bad-patent epidemic when the system itself was designed to make patents easy to challenge.

False Narrative #3: Patent Owners Who Don’t Make Products Are “Patent Trolls.”

Few terms have done more damage to public understanding of the patent system than “patent troll.” It’s a clever insult, conjuring an image of someone lurking under a bridge, waiting to demand money from innocent travelers.

But who exactly qualifies as a patent troll? An inventor who develops a breakthrough technology but doesn’t have the resources to manufacture it? A university that patents discoveries made in its laboratories and licenses them to companies that can turn them into commercial products? A small business that sells its patents to raise capital? An investor who purchases patents from a struggling inventor? Or a company that acquires patents and licenses the technology to others?

None of these activities is abusive. They are essential parts of the innovation economy.

Not every inventor can or should become a manufacturer. We don’t expect every songwriter to own a record label, every author to operate a publishing house, or every architect to own a construction company. Why would we expect every inventor to own a factory?

Inventing something and manufacturing it are two very different undertakings, requiring different skills, resources, and investments. Our patent system recognizes that distinction. An inventor can develop a new technology, disclose it to the public, obtain a patent, and license the invention to someone better positioned to commercialize it.

That’s not a defect in the system. It’s one of its greatest strengths.

Calling someone a patent troll tells us nothing about whether their patent is valid, whether it has been infringed, or whether their enforcement conduct is improper. Those are the questions that actually matter.

Blame the Patent Owner. Excuse the Infringement.

There is a common thread running through the narratives about “bad patents,” “patent trolls,” and supposedly defective patents canceled by the PTAB. They all shift the focus away from the conduct of those accused of using patented inventions without permission and onto the patent owners seeking to protect their rights.

If a patent owner can be dismissed as a troll, why worry about whether its patent has been infringed? If a patent can be characterized as bad, why worry about the consequences of weakening its protection? And if a PTAB decision can be portrayed as proof that the government issued a worthless patent, why question the lower evidentiary burden and deferential appellate review that helped produce that result?

The accusation becomes the defense. The patent owner becomes the problem. And the alleged infringer becomes the victim of an unfair system. It’s a remarkable reversal.

America should have a patent system that issues valid patents, resolves disputes fairly, and discourages abusive litigation. But we should stop confusing the enforcement of property rights with the abuse of those rights.

And we should recognize the campaign against “bad patents” and “patent trolls” for what it is: a convenient way to blame patent owners and excuse infringement.

    Thanks, Coke and I’m happy to see the comments from others on this.

    Certainly, there are cases of abuse, but the label “patent troll” turns a criticism of particular conduct into a judgment against an entire commercialization model. It’s just not productive and devalues IP rights rather than enabling investment and collaboration (which should be our goal!).

    To put it succinctly, it’s as unhelpful to assume “no patent owners ever misbehave” as to automatically “blame the patent owner.” Both sides can be right at the same time, both can point to obviously bad behavior at either end of the spectrum. The hard part is the sorting. I agree with you that the pendulum swung way too far against patent owners, but it’s crucial to understand that the other side’s gripes are legitimate as well.

    Dear Ms. Stewart –

    Some of this is counterfactual, some is correct at its center, but fails to recognize that correctness does not extend to the whole universe of fact patterns. I’m as pro patent as anyone, but I still acknowledge the existence of patent trolls, and I think it harms the pro-patent side to deny the reality.

    There’s a spectrum from the most virtuous patent owners to the most egregious patent trolls. The real problem is that it’s difficult to draw the line—as difficult as to draw a precise line for “short” vs “medium” vs “tall” height. But the phenomenon is unquestionably real. It’s counterfactual to deny that egregious bad behavior exists at one end of the spectrum, as counterfactual as if one were to deny the existence of tall men. It’s counterproductive to pretend that the law that governs disputes between two virtuous parties that start with different facts and views of facts extends to the entire spectrum. Some parties exploit the rules to nonvirtuous ends.

    When I was in-house, we had several troll suits. As outside counsel I’ve defended them. Some of the characteristics are –
    * the first contact is a summons and complaint
    * demand letters that clearly reflect absence of investigation of the accused product
    * a claim interpretation that is well outside the bounds of principle
    * after the accused infringer writes back with either a showing of non-infringement or dead-on prior art, the follow-on letter doesn’t engage on the merits, but just says something like “well, our license demand is only x, which is far less than litigating.”
    * the patent owner’s follow-on letter that takes a position that is flatly contradictory to earlier positions (or contrary to the prosecution history).

    No one of these is deterministic—any one of these could happen in a virtuous patent assertion. But when you’re defending one of these cases, within a couple weeks, it quickly becomes clear beyond question that the patent owner isn’t playing the game fairly, and is just arbitraging the cost of litigation. It’s not helpful to deny existence of nonvirtuous actors.

    The difficulty is drawing the line.

    Understanding the purpose and use of IP rights has always been a challenge for inventors, content creators, investors and policymakers. It shouldn’t be.

    Lack of clarity, disparate narratives and uncertainty benefit those who fear competition from owners of strong IP rights. It continues to confuse people how some businesses can have tens of thousands of patents and still campaign for their uncertainty.

    Discussing IP requires context, which is often lacking in the IP discussion. At the Center for Intellectual Property Understanding (CIPU), we strive to provide context and give people an opportunity to make up their own minds about what benefits innovation and how.

    Great article!
    Thanks for excellently exposing the major myths, false narratives, and double-standards on patent enforcement.

    I would correct, however, the explanation of the falsehood of Narrative #2 — that high patent cancellation rates at the PTAB prove that the USPTO issues “Bad Patents.” Of course, it proves nothing of the kind.
    While the PTAB’s lower evidentiary burden and the deferential appellate review the author mentions make challenging patents easier at the PTAB, those are not the reasons for the high rate of cancelled patents at the PTAB. The rate at which adjudicated patents are found invalid typically ranges around 50 percent, but that has nothing to do with the quality of all patents issued by the USPTO. This is because these are a small minority of patents especially selected for adjudication, precisely because they are not representative of all other issued patents.

    The reasons and factors that govern the outcomes of patent validity adjudications are solely reflective of the litigants’ divergent expectations in uncertain cases with “close calls.” This results in selection of only those special cases for litigation. In cases in which there is more certainty — patent holder and its challenger similarly perceive the likely outcome (judged valid, or invalid), there would be no appreciable divergence of expectations of the parties as to the outcome of the litigation and they will settle with no adjudication.

    I explain this probabilistic dynamic in my article “Fallacy dispelled: invalidation rates of adjudicated patents convey nothing about quality of all issued patents,” “IPWatchdog (August 20, 2025)”, and in “my follow-up response rebuttal”.

    The narrative about “bad patents” is nothing new. Some authors have published statistics purporting to show that the USPTO has substantially higher grant rate than other national patent offices for the same inventions, and alleged that this indicates USPTO’s poor quality examination. The problems with those studies is their flawed methods of deriving comparative patent grant rates, as I explained in my article “Bad Science in Search of ‘Bad’ Patents,” 17 Fed. Cir. Bar J. 1 “(August 2007)”.

    Even occasions where actual “bad patents” are asserted — patents with improperly overbroad claims that should not have been issued — those patents do not impose substantive costs on businesses and consumers because the industry is able to properly vet and analyze the claims, and move forward under Freedom to Operate Analyses assurances. John Howells and I detail the history of such example in our article “Freedom to Operate analysis as competitive necessity—the Selden automobile patent case revisited,” 19 J. Intell. Prop. L. & Pract., 493 “(June 2024)”.

    Thank you for your well considered and frank article. The damage that has been done to inventors and small companies over the last 15 years is incalculable. A good example is the company Netlist who has had patent after patent reviewed by the efficient infringers over that 15 year period. This has cost the company multiple of millions of dollars which could have been spent in creating great technology and jobs. Today those big corporations are now licensees of Netlist and there are others who will try to abuse the system whenever they can. It’s refreshing to know that the Ptab under director squires is changing the way they have operated in the past.
