USPTO PatentsView assignee record - 249 granted patents across 11 technology areas, active 2018–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H04L (TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION).
The verdict
Slack holds 249 US patents across 11 technology areas, rank #1,651 of 50,000 tracked assignees.
Slack Technologies, Llc has been granted 249 US utility patents between 2018 and 2025, placing Slack Technologies, Llc at rank #1,651 across all assignees tracked by PlainPatent. This portfolio spans 11 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, Slack Technologies, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Slack sits between Valinge Innovation AB (250 patents, rank #1,647) and Amadeus S.a.s. (248 patents, rank #1,655) - the closest US assignees by grant volume. The composite Innovation Score of 49.9/100 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 237 grants, compared with 12 in the 2015–2019 window, a +1875% 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. Slack Technologies, Llc's 19.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Slack Technologies, Llc against peers pursuing similar technology classes.

How to use this portfolio
Slack's 249 grants land it in the top 14% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
