Panasonic’s patents were used in 60k+ rejections since 2000

We monitored patent publications of Panasonic for the past 20 years at the USPTO. Its patent portfolio shows that they have their footprints in 68 different technology areas ranging from Semiconductor/Memory to Graphic User Interface and Document Processing.

Below are the top technology areas of their interest – 

Technology AreasNumber of Applications
Semiconductors/Memory4183
Selective Visual Display Systems3223
Optics2464
Electrical Circuits and Systems2231
Graphic User Interface and Document Processing2067
Electronic and Commerce1845

Since they have patents covering a wide array of technologies so we thought why not check which type of companies are getting blocked by these patents. 

Refer to the table below for more information:

Number of Blocked Assignee6058

Which assignees faced the most rejections?

Interestingly, ~60000 rejections (102/103) were given based on Panasonic’s patents. It would be even more interesting to see which companies are getting rejections based on Panasonic’s patents.
