Further reading

  • Bilski v. Kappos (2010)

    Machine-or-transformation isn't the only § 101 test, business-method patents survived as a category, and the specific Bilski hedging method was unpatentable. The trio of Bilski, Mayo, and Alice gave defendants the modern § 101 motion.

  • Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co. (2002)

    Narrow your claim during prosecution and you presumptively give up the equivalents in between. The presumption is rebuttable, but in practice the prosecution history is a defendant's gold mine.

  • § 285 attorney-fee shifting in practice

    § 285 isn't a guaranteed remedy. It's a high-effort, high-evidence tool that pays off occasionally and dramatically — turning a $3M defense expense into a $3M plaintiff bill.

  • eBay Inc. v. MercExchange (2006)

    Pre-eBay, an injunction was a kill switch a patent holder could threaten. Post-eBay, the worst is monetary damages — and for an NPE that wants license fees anyway, the four-factor test usually fails on the irreparable-harm prong.

  • How to obtain a patent

    The USPTO process takes 2-3 years and costs $10,000-$15,000. The patent that comes out the other end is only as valuable as your willingness to spend much more enforcing it.

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.
