Cuozzo Speed Technologies, LLC v. Lee

After the Patent Trial and Appeal Board invalidated Cuozzo's (plaintiff's) speedometer patent as obvious during inter partes review requested by Garmin, applying the Patent Office's broadest-reasonable-construction claim standard rather than the ordinary-meaning standard courts apply in patent-validity litigation, Cuozzo argued the board used the wrong standard; the Federal Circuit rejected that argument and upheld the Patent Office's regulation as a valid exercise of its rulemaking authority.
