A tribunal Congress built to kill bad patents is turning challengers away at the door, at the discretion of one presidential appointee, using rules never put to public comment. Intel and Google want the Supreme Court to stop it. The fight is technical, but the principle underneath is simple: who decides who gets their day in court.

The headline reads like inside baseball for patent lawyers. Intel and Google ask the Supreme Court to vacate a Federal Circuit ruling about the Patent Trial and Appeal Board. Skip it and you miss one of the more important administrative-power fights in the country right now, because the real question is not about patents. It is about whether a single agency official can quietly shut a door Congress deliberately built, and whether any court is allowed to check him.

Here is what is actually happening, in plain terms.

What the PTAB is, and why it exists

In 2012, under the America Invents Act, Congress created the Patent Trial and Appeal Board, an agency tribunal where companies can challenge the validity of patents through a process called inter partes review, or IPR. The logic was straightforward. Bad patents, ones that never should have been granted, are expensive weapons. A patent troll can wave a shaky patent at a company and extract a settlement, because fighting it in federal court costs millions and takes years. IPR was meant to be the faster, cheaper venue to test whether a patent is actually valid.

Tech companies love it. Patent owners, especially those who make money asserting patents rather than building products, hate it. Both reactions tell you it is doing roughly what Congress intended: it kills patents that cannot withstand scrutiny.

Congress wrote exactly one timing limit into the statute. If you get sued for infringement, you have one year to file your IPR petition. That is the deadline Congress chose. Remember it, because the whole dispute is about a second deadline nobody voted for.

The door that got quietly narrowed

Starting in 2020, Patent Office leadership began turning IPR petitions away before anyone examined whether the patent was any good. Not on the merits. On discretion.

The framework came from two PTAB decisions, NHK and Fintiv, that the Director designated as precedential, meaning binding on the Board. Under the NHK-Fintiv rule, the Board can deny a petition if there is parallel litigation in a district court that is far enough along. The practical effect is brutal for challengers. Patent owners like to sue in the Eastern District of Texas, where the average time to trial is about 22 months. Under the discretionary rules, that can leave a defendant roughly four months to file a validity challenge before the case is deemed too advanced to bother reviewing.

Read what that does. Congress said you have one year to file. The Patent Office effectively created a faster-than-time-to-trial deadline on top of it, and if you miss that shorter, invented window, your challenge is refused without anyone asking whether the patent is valid. As Google's petition frames it, the agency now treats petitioners as misusing the system simply by defending themselves in court while also seeking review, a bind the petitioner cannot escape because it does not control whether a court pauses the lawsuit.

The scale is not trivial. Since the newer timing rules took hold, a reported 770 IPR or PGR petitions have been denied for discretionary reasons. That is 770 validity challenges turned away at the threshold.

The legal argument, translated

The companies, Intel, Google, and in the related Federal Circuit case Apple and Cisco too, are making an administrative-law argument, and it rests on a distinction that sounds dry but decides everything.

Under the Administrative Procedure Act, if an agency wants to make a substantive rule, one that binds parties and alters legal rights, it must go through notice-and-comment rulemaking: publish the proposed rule, let the public respond, and account for the feedback. If it is merely a general statement of policy describing how the agency intends to use its discretion, it can skip all that.

The companies say NHK-Fintiv is obviously the former. It is outcome-determinative, it dictates results, and it was adopted with none of the public process the law requires. The government says it is the latter, just guidance describing how the Director exercises a discretionary power, binding nobody with the force of law. When the Patent Office asked for feedback on discretionary denials, more than 800 comments poured in, which rather undercuts the idea that this is a minor internal policy of interest to no one.

The deeper objection, raised by the PTAB Bar Association, cuts to a constitutional nerve. The statute the agency cites for its discretion, Section 314(a), is being read as a grant of legislative authority to invent new denial factors, when it was written as a limit on when the Director may institute review. In other words, the agency took a leash Congress handed it and used it as a license.

The catch-22 that makes this so hard

Here is the wrinkle that turns a normal legal dispute into a genuine constitutional problem, and it is the reason the case matters beyond patents.

The Supreme Court has repeatedly held that PTAB decisions about whether to institute review are not appealable. The statute deliberately shields those threshold decisions from judicial review, to keep the process fast. That made sense when institution was a routine screening call. But now the Director is using that same unreviewable institution power to enforce a sweeping, self-made policy, which means the policy inherits the shield. The agency makes a rule without public process, applies it to slam the door, and the door-slam is by law immune from appeal.

The companies have tried to get around this with mandamus petitions, an extraordinary request asking a court to order an agency to follow the law. The Federal Circuit has been unreceptive. It denied the first six mandamus petitions without oral argument, and in late February 2026 rejected five more in a matter of days, from petitioners as varied as Intel, Tesla, an ed-tech firm, and a Chinese communications company, each with a different theory, none successful. A former acting Patent Office director put the danger bluntly: he worries the agency could win, or effectively win, and simply keep issuing summary denials, because if the mandamus remedy is nonexistent, the outcome may not matter. An unlawful rule you cannot appeal is, functionally, an unreviewable one.

The detail that should make everyone uneasy

Buried in Google's brief is a fact that deserves far more attention than it has received. The Patent Office has indicated it will bias its discretion against foreign-backed petitioners, but not against foreign-backed patent owners.

Sit with the asymmetry. The same agency that says its discretionary framework is neutral policy has signaled it will weigh a challenger's foreign backing against them, while extending no such skepticism to foreign entities that own patents. Whatever one thinks of the broader fight, an agency openly tilting access to a federal tribunal based on who is behind the filing, on one side only, is the kind of thing administrative process exists to catch. It is precisely the sort of consequential judgment that is supposed to survive public comment and judicial scrutiny, not arrive by memo.

Why the timing favors the challengers

There is a reason this fight is landing now, beyond the Trump-era Patent Office reviving and expanding the denials. In 2024, the Supreme Court decided Loper Bright, which sharply reduced the deference courts owe agencies interpreting their own statutes. For decades, an agency reading an ambiguous statute got the benefit of the doubt. After Loper Bright, courts decide the statute's meaning for themselves.

That changes the math. A patent-law professor noted that a Federal Circuit ruling too deferential to the Director could face harsher scrutiny if it reaches the Supreme Court under the new standard. The companies are, in effect, betting that the current Court's skepticism of agency freelancing extends to the Patent Office. This is not just a patent case. It is the administrative-power revolution of the last few years pointed at a specific, unusually well-defended agency practice.

What is really at stake

Strip away the acronyms and the case asks a question that has nothing to do with patents specifically. When Congress builds a process and sets its limits, can a single agency appointee layer on new limits Congress never authorized, adopt them without the public input the law requires, and then hide the whole thing behind a statutory shield against appeals?

If the answer is yes, the model travels. Any agency with an unreviewable threshold decision could use it to enforce whatever policy it likes, immune from both the rulemaking process on the front end and judicial review on the back end. That is why trade associations, the PTAB bar, retailers, and manufacturers have lined up behind the challengers.

The patent angle is what got them in the door. The precedent is what they are afraid of.

Whether the Supreme Court takes the case is its own question; the Court has turned away earlier versions of this fight more than once, and a denial signals nothing about the merits. But the issue is not going away, because the underlying tension, fast unreviewable agency discretion versus the public process the law demands, is only sharpening. Intel and Google are asking the Justices to decide who guards the door to a court Congress built. The answer will matter well beyond the people trying to invalidate a patent.
