    The claim chart is where the plaintiff's case actually lives. The complaint is a pitch deck; the chart is the homework — and most patent troll homework doesn't survive a careful read.

  • 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.

Not every patent holder is a “troll”

Not all companies that litigate their patents are patent trolls. A patent troll — technically a Non-Practicing Entity (NPE), sometimes called a Patent Assertion Entity (PAE) — is a person or entity that acquires patents (often broad or vague ones) not to produce goods, but to extort licensing fees or settlements from companies through threats of infringement litigation. Many patent owners enforce their patents legitimately to protect real products, technologies, and research investments they have actually made. The analyses on this site are tools for evaluating any patent assertion on its merits — not blanket accusations against every patentee.
