Technology Center | Renewal Rate (First Fee Paid) | |
1600 | Biotechnology and Organic Chemistry | 81% |
1700 | Chemical and Materials Engineering | 86% |
2100 | Computer Architecture Software and Information Security | 90% |
2600 | Communications | 90% |
2800 | Semiconductors, Electrical and Optical Systems and Components | 89% |
3600 | Transportation, Electronic Commerce, Construction, and Agriculture | 82% |
3700 | Mechanical Engineering, Manufacturing and Products | 84% |
The table above reports the percentage of patents for which the first maintenance (renewal) fee was paid. The chart includes patents issued 2005-2007 and the results are grouped according to technology center. It is somewhat interesting to me that TC1600 has the lowest renewal rate.
