Patent Intelligence · Claim Evolution
Are patents getting broader or narrower?
The number of claims in a patent is a rough proxy for how broadly the inventor tried to protect their invention. More claims = wider protection. How has this changed since 2010? Which domains are writing broader IP today than they were a decade ago?

What claim count measures
Each claim in a patent defines a distinct scope of protection. More claims = more chances to catch infringers (different claim types cover different embodiments), but also more prosecution cost and more opportunity for the USPTO to invalidate individual claims. High claim counts are an aggressive protection strategy.
Why broadening ≠ bad
Broader filings (more claims) often indicate that inventors and their attorneys are getting more sophisticated at capturing every dimension of an invention. They may also reflect the trend toward continuation patent families — filing multiple continuations with different claim sets to build a defensive moat.
Domain variation explained
Pharmaceutical patents tend to have more claims because each formulation variant, dosage form, and method of treatment can get its own claim. Software patents are constrained by Alice doctrine, which invalidates abstract software claims, leading to tighter average counts. Biotech sits in between.
