This dataset covers 601 published records matching analytical instrumentation search terms across the 2015-2026 window. The figure includes patent families tracked in the assignee ranking, not just granted patents, and covers filings across multiple receiving offices including the United States, WIPO, Europe, India, Canada and Australia. Because publication lags filing by roughly 18 months, the true count for the most recent one to two years will rise as later applications are indexed.

The dataset ranks 100 companies by patent family count, with a single leader holding 35 records and a gradual drop-off through the ranked field — fifth place sits at 22 records and tenth at 17. The top five assignees combined account for 24.3% of all 601 records, and the top ten for 40.3%, meaning concentration exists but does not amount to control of the field by a small handful of players. Beyond the ranked leaders, filing spreads across a long tail of companies and institutions with only a few records each.

Material analysis and testing, IPC subclass G01N, appears on 59.4% of the 601 records in scope, making it by far the most heavily claimed area. Life-science-adjacent measurement classes — C12Q for enzyme and DNA testing, B01L for lab apparatus, A61B for diagnosis and surgery, and C12M for bioreactors — each cover roughly 7-11% of records, showing meaningful overlap between physical sensing and biological measurement. Electric and magnetic measurement (G01R) and digital data processing (G06F) are present but smaller shares of the corpus.
