Portfolio overview
Rockford Corporation has been granted 11 US utility patents between 2015 and 2025, placing Rockford Corporation at rank #25,061 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 claims per patent with primary concentration in H04R (LOUDSPEAKERS, MICROPHONES, GRAMOPHONE PICK-UPS OR LIKE ACOUSTIC ELECTROMECHANICAL TRANSDUCERS; DEAF-AID SETS; PUBLIC ADDRESS SYSTEMS). As a US Corporation, Rockford Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Rockford sits between Ringers Technologies Llc (11 patents, rank #25,057) and RSA Protective Technologies, Llc (11 patents, rank #25,065) - the closest US assignees by grant volume. The composite Innovation Score of 33.9/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 8 grants, compared with 3 in the 2015–2019 window, a +167% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. Rockford Corporation's 9.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Rockford Corporation against peers pursuing similar technology classes.

- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
