Does more volume mean deeper claims for Beijing?
Each dot is one of Beijing’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Beijing’s own 14.9 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Beijing's grants concentrate
Beijing E-Town Semiconductor Technology Co., Ltd. is a focused PatentsView assignee: 26 CPC subclasses with 83.2% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10).
