Browse a bit - if you are involved in the patent industry, we think you'll find something of interest.


We have complete ready-to-use search systems including custom hardware and software for your office or multi-office intranet, or the Internet for your customers. Systems are available for as few as 10 and scale up to as many as 1000 simultaneous users. This is not a scaled-down version of our online systme.

Same US Patents, Different CPC Classifications.   WHY? 

The USPTO MCF data began in late 2015, and almost immediately we noticed differences between the MCF and DOCDB for the same US patents. The differences were not trivial. 30 days later we started our project to track and analyze these differences. 

We mistakenly assumed that the USPTO sent DOCDB updates to the EPO with CPC classes in them, and the EPO used them.  But as it turns out, US patents are classified by both authorities, and not always in the same Groups and Sub-Groups. A small number were even found to be in totally different sub-classes and a few were not even in the same class  (all of these appeared to be mistakes and were fixed fairly quickly). 

Early results indicated it was a learning curve. The EPO had a decent headstart with the new CPC since it has its roots in ECLA, the EPO's previous system, with both based on the ST.8 standard (with minor differences). For the USPTO, it was a brand new ball game with a different set of rules. Frankly, the thought of training 9000 or so examiners on a new Class system in 12 to 18 months conjureed up images of hearding cats...  while wearing a blindfold. To the USPTO's credit, we began to see far fewer differences in less than 8 or 9 month (summer of 2016).  We are now headed into the winter of 2017, and thankfully, they are growing even closer.  

If you build your own search system, this could be a problem for your searchers. If not, does your current search provider index both sets?

Searching by classification is the most popular method for professional searchers, and depending on the type of search, a good searcher will often "eyeball" EVERY document in the Sub-Groups of interest. This can be hundreds of documents, or even a thousand or two depending on the technology.

The following questions remain:

1)  Whose CPC data is more accurate?

2) They will ever match exactly- No-  so how close will they get?

3) How will this affect your class searches?

4) Is it wise to index both sets of CPC data into one system?  (we think so - just ignore the duplicates!)

5)  CPC data for Reissue patents is still not included in the U.S. MCF. Will it ever be?

We will continue to acquire Reissue CPC data from DOCDB for our subscribers in our standard CSV file format until the USPTO supplies it.
