The patent collection was an automated procedure, and no manual filtering of the patents was done. For collecting the data, we used the connected car (automated car) terminologies such as vehicle-to-everything (V2X), vehicle-to-infrastructure (V2I) , vehicle-to-network (V2N), vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), vehicle-to-device (V2D) and vehicle-to-grid (V2G), few other relevant key terms, and broad classes related to telecom concepts. We formulated custom search logics based on a combination of identified key terms, concepts, and classes. In addition to that, we made some standard related queries (Eg: (NAME/STDN=”ETSI-TS-22-186″) for all the v2x relevant standards including protocol layer standards by restricting that with V2x key terms). We ran all these search logics on Questel Orbit (patent database) which yielded a patent set of around 12K unique patent families which would broadly consist of all V2X related patents.
5G Automotive Association (5GAA) defines its purpose to increase road safety, traffic efficiency, and energy savings. Thus, with the rise of 5G technology, companies are ramping up their developments in various areas that have been birthed by it, and V2X is one of those hotspots today. Finally, we ran all possible search logics on Questel Orbit (patent database) which yielded a patent set of around 12358 unique patent families which would broadly consist of all V2X related patents. As this is completely automated process, +_ 5% tolerance can be considered.

As this is a primary analysis, we haven’t categorized the patents based on 5G / 4G technology. At this point of time, we cannot confirm the essentiality of the declared SEPs, as technical specifications covering this domain are still under development. But there is a high probability that these patents will prove to be essential to standards. But still we are providing insights to probable percentage of SEP patents and CR data based on Orbit & data available in 3gpp site respectively. As the rel-17 documents are not completely available, we have restricted our searches to rel-14, rel-15 & rel-16 only.
