Thanks for the 5 stars!

Petapator has been receiving more 5 stars from the user community lately.  It is a recognition of our hard works.  We will keep improving it!

The next release will focus on analytical tools.  There are some setbacks as our servers are struggling to handle the volume of traffic during the load test.  We are reviewing the design and planning to install more servers.  More details will posted here later.


Road map of Petapator

The next release of Petapator will focus on the ultimate challenge: increasing patent search speed.  In our daily use, I believe searching claim text and analyzing searching results are very important.  Unfortunately, USPTO full-text search is slow, especially with claims and descriptions.  Further, USPTO does not offer any analyzing tool now and the analyzer at Petapator is only limited to the search results appearing on the screen.

The next release, in our humble opinion, will be revolutionary.  Full-text with wildcard and proximity (for example, “protein acid”~10 will search for patents that have the words “protein” and “acid” within 10 words from each other) search results should be available within 5 seconds for 8 million US patents (for patents with patent number larger than 4,000,000) and patent applications (since 2001).  Analytical results on average will be available within 10 seconds.  Our goal is to cut down the current processing time by half before releasing the next version.

In order to provide the full-text search, a lot of effort has been spent on collecting the patent information.  Additionally, we need to deploy a dozen servers to make the search and analyzing features to the public.  We may need to start charging.

We will keep blogging the development.  If you are interested to use the new version before the general release, please email us at


Petapator 7.0 is just released

There are two main new features in Petapator 7.0: Find and Quicker Results


The first one feature is a new Find function to highlight and find words in the search results.  To use this feature, simply press CTRL-SHIFT-F or click on the Find button at the top-right corner.


You can search up to four words/phrases at the same time.  Technically, we can add unlimited words/phrases for you to search.  We believe four are enough and should not make the user-interface become friendly.  If you have any suggestion to improve the user-interface, please let us know.

Quicker Results

The search function is  powered by USPTO server that we cannot improve.  This is why if you have a complicated query, especially with full-text search, the search is slow.  But once the search results are ready, our servers are then used to parse patent information and convert figures from PDF and TIFF format to PNG format.  You should now see the patent information come out much quicker.  This is because we have tripled the number of servers to handle the increasing traffic.    If you are still experiencing slow responses, please let us know.
