Portfolio overview

Polk Audio, Llc has been granted 20 US utility patents between 2015 and 2025, placing Polk Audio, Llc at #14,870 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 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, Polk Audio, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Polk sits between Pictech Management Limited (20 patents, rank #14,862) and Purdue Pharmaceutical Products L.p. (20 patents, rank #14,870) - the closest US assignees by grant volume. The composite Innovation Score of 42.7/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 8 grants, compared with 7 in the 2015–2019 window, a +14% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Polk Audio, Llc's 12.2 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 4 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
