U.S. patents, contrary to what may be expected, are essentially vague documents where engagement with the reader is minimized. In general, patent drafters typically exploit several vagueness strategies with the purpose of concealing information that may enable their competitors to claim alternative inventions. Within a Discourse Analysis and Applied and Corpus Linguistics framework, this chapter describes some likely incongruities between the legal requirements for the disclosure of the invention and the actual language used in U.S. patents, and illustrates them with examples from a corpus of 1,001 samples. Finally, linguistic corpus evidence is linked to justifications for non-disclosure provided by scholars from diverse fields such as Applied Linguistics, Rhetoric, Economics, Philosophy, and Law.
