Filing activity in Control & Regulation has accelerated, with the most recent five years averaging about 9 new patents per year — roughly 40% above the earlier window. Acceleration often correlates with a technology shift attracting fresh corporate R&D, and it tends to push expiration cliffs further out as new filings replace older ones.

What Expirations Mean for Control & Regulation

As patents in Control & Regulation expire, the underlying methods and apparatuses enter the public domain. Competitors gain freedom to operate without licensing the original claims, and downstream products incorporating the formerly protected technology can ship without a royalty stack. This is the ground-truth mechanism that drives generic-drug economics and the broader competitive dynamics in semiconductor process generations and consumer electronics platforms.

For pharmaceutical and biotech CPC classes, drug-specific exclusivities tracked in the FDA Orange Book can delay generic entry past patent expiration. For non-drug technology classes, expiration is a cleaner trigger — competitors generally gain freedom-to-operate immediately. Either way, the underlying expiration math comes from USPTO records.

How This Patent Landscape Is Built

Patents are assigned to Control & Regulation based on their primary CPC classification (G05) as recorded by USPTO examiners. Total counts include all patents in the tracked dataset that carry this CPC prefix; recent-patent and yearly-trend tables are derived from the same record set. Each company\'s grade reflects its overall Patent Strength Score across its entire tracked portfolio, not just patents in this CPC class. Read the full methodology for the data pipeline, score weights, and known limitations.

Frequently Asked Questions

What is the Control & Regulation CPC class?

Control & Regulation corresponds to Cooperative Patent Classification (CPC) prefix G05, the international system used by the USPTO and EPO to organize patents by technical subject matter. Patent landscape for Control & Regulation technology (CPC class G05). Covers innovations in control & regulation from leading companies worldwide. CPC classes are assigned by patent examiners and update as the technology evolves, so the patent set tracked here reflects the current classification of every included patent.

Who are the top patent holders in Control & Regulation?

Siemens (56 patents), Honeywell (55 patents), Boeing (40 patents), Ford (35 patents), Tesla (9 patents) are the leading holders in Control & Regulation. Patent counts at the company level are useful for spotting concentration, but they do not tell you about claim strength — for a finer signal, see each company's Patent Strength Score grade in the table below.

How many Control & Regulation patents will expire soon?

Per-year expiration counts for this technology class can be derived from the recent patents table on this page combined with each patent's expiration date — patents typically expire 20 years from earliest non-provisional filing. For year-by-year expiration totals across all CPC classes, see the expiring-year pages on this site, which break down each year's cohort by company and technology.

What happens when patents in Control & Regulation expire?

When a patent expires, its claims enter the public domain. For Control & Regulation, that means competitors can implement the underlying methods or apparatus without licensing fees. The practical impact varies — in regulated areas like pharmaceuticals, FDA-granted exclusivities can extend market protection past patent expiry. In unregulated technology areas, expiration usually translates directly into freedom-to-operate for new entrants.

Where does Control & Regulation patent data come from?

All patent data is sourced from the U.S. Patent and Trademark Office through the PatentsView and Open Data Portal APIs. CPC classifications are assigned by USPTO examiners and are part of the official patent record. Verify any individual patent through USPTO Patent Public Search (ppubs.uspto.gov) or Google Patents.
