Google has filed 42657 patent applications at USPTO so far (Excluding Design and PCT applications). Out of these 34188 have been granted leading to the grant rate of 87.09%.
Below are the key stats of Google’s patent prosecution at the USPTO:
Interestingly, the average grant time of Google’s patent applications is less than 3 years(2.98 years to be precise). This is fairly shorter than the average grant time of 3.23 years of the art units where Google files patent applications.
Now let’s have a look at how does Google fare when compared with the average grant index of USPTO and Art Units of their interest.
Allowance rate of top 10 Group Art Unit (GAUs) of Google’s interest:
| GAU | Total Applications | Allowance Rate |
| 2617 | 689 | 88.82% |
| 2618 | 459 | 88.77% |
| 2161 | 428 | 92.86% |
| 2665 | 424 | 95.37% |
| 2611 | 419 | 94.87% |
| 2163 | 381 | 90.93% |
| 2162 | 374 | 90.99% |
| 2659 | 367 | 88.89% |
| 2657 | 366 | 91.29% |
| 2168 | 360 | 89.37% |
Only 4 out of the top 10 GAUs of Google have the allowance rate less than 90%.
