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.
AI prior art search tools: a 2026 buyer's guide for defendants
