Patent trolls in 2025: the year in numbers
2025 was a banner year for patent trolls — and not by accident. Filings surged while the defendant's cheapest weapon, the PTAB, was quietly taken off the table. Here's what the reporting shows, and why the two are connected.
Patent reviews: IPR, PGR, and reexamination
Suing in district court to invalidate a patent costs $3-5M and takes years. The USPTO's post-grant review system does it for $200-500k and 12-18 months. For a defendant facing a weak patent, the choice is usually obvious.

Most-litigated US patents: 12 patents that defined the patent troll era
If a demand letter lands on your desk citing one of these, you are not the first. The campaign playbook is on file. The defenses other defendants used are public record.
