Portfolio overview

Nortonlifelock Inc. has been granted 191 US utility patents between 2019 and 2023, placing Nortonlifelock Inc. at rank #2,073 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.3 claims per patent with primary concentration in H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION). As a US Corporation, Nortonlifelock Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Nortonlifelock sits between Saint-gobain Abrasifs (192 patents, rank #2,069) and Autostore Technology AS (190 patents, rank #2,077) - the closest US assignees by grant volume. The composite Innovation Score of 46.9/100 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 189 grants, compared with 2 in the 2015–2019 window, a +9350% 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. Nortonlifelock Inc.'s 19.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nortonlifelock Inc. against peers pursuing similar technology classes.

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.
