Top 50 Companies for Patent Quality

At Patent Bots, we proofread an entire year of issued patents and then ranked 676 companies by the smallest average number of errors in the issued patents.

Congratulations to these companies for doing amazing work! To improve your company's patent quality scores, use Patent Bots automated proofreading to remove errors in your work.

Office Action Rejection Data

At Patent Bots, we provide patent examiner statistics to help patent attorneys get better outcomes for their clients during prosecution. One part of our statistics is the Recent Dispositions tab where you can see a list of recent allowed and abandoned cases for your patent examiner.

I find it particularly helpful to have easy access to recent patents allowed by my examiner. If I am having trouble persuading an examiner to allow claims, I look at recently allowed patents by that examiner and review the successful arguments made there. This way, I can learn from other patent attorneys and hopefully get a better outcome for my client.

We've added a new feature to make this process even easier. Our Recent Dispositions tab now includes a list of office actions and the rejections made in each office action:

With our office action rejection details, you can quickly find the arguments you need. If your only rejection is 101, then skip the first patent above and go to the second one. Further, for a particular patent, some office actions may have 101 rejections and others may not and can go directly to the ones that do.

As a bonus, the View button on each row takes you directly to our PatentPlex page for the patent that includes the image file wrapper. When we show you the image file wrapper, we again show you the list of rejections for each office action:

As another bonus, we've made our image file wrapper retrieval much faster and more robust. It now works even when PAIR is not working.  It is More Reliable than PAIR!^TM
