Trends

What is being patented, and how it fares

Topics read from the titles of 7,648,559 applications, independent of how the office classified them: 8,000 topics that recur, each with its filings by year, its allowance rate and its time to a first action. A topic is rising when its share of new filings in the last two years is at least half again what it was in the four years before.

Any phrase works, not only the topics listed here: the record is searched and the figures computed on the spot.
