USPTO: No clear winners in 5G patent filings; caution urged when reviewing claims of “5G dominance”
A report published in February 2022 examines which companies have filed for patents at the USPTO (US Patent and Trademark Office) in four technologies: Management of Local Wireless Resources, Multiple Use of Transmission Path, Radio Transmission Systems, and Information Error Detection or Error Correction in Transmission Systems. USPTO says that approach narrowed the focus to patent flings on technologies central to 5G innovation. The report concludes that there’s no clear lead to be seen: “The findings of the report call into question claims that any single firm or country is ‘winning’ the 5G technology race.“
Six companies topped the results, none with any notable lead. They were: Ericsson, Huawei, LG, Nokia, Qualcomm and Samsung. The report notes that while ZTE often is mentioned as a competitor to those six firms, it filed far fewer patents outside of China during the study period. The report authors did a textual analysis of the 22,000-plus patent filings studied to see if any of these competing firms stood out in particular attributes. Here, more subtle differences emerged.
Qualcomm’s patents had the most “legal breadth,” in the sense of making shorter (and therefore generally broader) claims about covered inventions; Ericsson and Nokia ranked higher for “radicalness,” meaning they cited less prior art as references; and Qualcomm and Samsung did well on “technical relevance,” or how often other patents cited their own patents or applications as prior-art references.
The USPTO report references a January 6, 2021 directive from the NTIA (National Telecommunications and Information Administration), the “National Strategy to Secure 5G Implementation Plan,” in which the NTIA sought “an informed understanding of the global competitiveness and economic vulnerabilities of United States 5G manufacturers and suppliers.”
This line from the USPTO report is significant: “Given the complexity of the results, caution is recommended when reviewing media claims of 5G dominance.”

Here’s Statista’s take on leading 5G patent holders (as of February 2021):
An IEEE Techblog post from March 2021 examined claims that Huawei and Samsung were the leaders in 5G SEPs (Standard Essential Patents). Earlier related IEEE Techblog posts are listed in the References.
Even though there is no definition of 6G (while 5G standards and frequency arrangements are woefully incomplete), an April 2021 report authored by the Chinese Patent Office states that China currently holds 35% of all 6G patents worldwide. The report urged China to “utilize its technological advantage in 5G to continue staying ahead.”
