If the number of patents issued in the first quarter of 2018 is any indication, artificial intelligence technology companies were busy a few years ago filing patents for machine learning inventions.
According to US Patent and Trademark Office records, the number of US “machine learning” patents issued to US applicants during the first quarter of 2018 rose 17% compared to the same time period in 2017. The number of US “machine learning” patents issued to any applicant (not just US applicants) rose nearly 19% during the same comparative time period. Mostly double-digit increases were also observed in the case of US origin and total US patents mentioning “neural network” or “artificial intelligence.” Topping the list of companies obtaining patents were IBM, Microsoft, Amazon, Google, and Intel.
The latest patent figures include any US issued patent in which “machine learning,” “artificial intelligence,” or “neural network” is mentioned in the patent’s invention description (to the extent those mentions were ancillary to the invention’s disclosed utility, the above figures are over-inclusive). Because patent applications may spend 1-3 years at the US Patent Office (or more, if claiming priority to earlier-filed patent applications), the Q1 2018 numbers are reflective of innovation activity possibly several years ago.
