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 Areas | Number of Applications |
| Semiconductors/Memory | 4183 |
| Selective Visual Display Systems | 3223 |
| Optics | 2464 |
| Electrical Circuits and Systems | 2231 |
| Graphic User Interface and Document Processing | 2067 |
| Electronic and Commerce | 1845 |
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 Assignee | 6058 |
| Number of publications monitored | 40846 |
| Publications involved in rejections | 15528 |
| Number of 102/103 rejections | 60455 |
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.
