Patent PIPEline

CFL Patent PIPEline includes several distinctive features in the area of patent searching, not least the complete absence of a need for keyword/boolean searching.

Since February 2018 we have been using the high quality Lighthouse IP dataset for enhanced R&D, in particular in defaulting to CPC codes and including the abstract and first claim as can be see in our latest output PDF File.  Here we are searching in the years 2012-2017 in the EPO, WIPO and USPTO datasets.

The report illustrated is the result of starting with the ultrasonic surgical shears illustrative sample from the USPTO Examination Guide. The program is not using the title, but all the words in the sample with no user input other than the filename.  The same can be done with the entry of a patent or application number.  

The ranking on the left shows the number of terms  Patent PIPELIne has found in common between the sample and each document shown.  You can also see that all the documents returned have some rlevance to the initial query, and these are the only ones returned by the program from all the patents in the six years in the test set. You can also see that if this had been your idea, then you would quickly find out that Ethicon Endo-Surgery, Inc. had got there before you!  You can also see that this is a US activity.  All the EP and WO patents have also been searched.

This link shows the PDF we took to the PIUG Annual Conference in Atlanta 2017, where we were one of only two first-time attendees who were also speakers, presenting our companion program SpanMatch.  This shows some of the additional outputs available. 

Patent PIPELine is an API, so these screenshots are simply  indicative of what can be done with the output.  The programs use UTF-8 plain text and can return HTML, XML, JSON or whatever is desired by an end user.  The output displayed on page 2 of the PDF is actually working directly from the XML source files where the matched patents are found.

Here are some of the other features:

  • Search input is normally a description of the invention or an outline application, although it is possible to use a patent or application number instead.
  • The program performs automatic identification of all terminology in the search document.
  • Searching on all those terms; in  a full patent this can be over 2000 terms.
  • Results are ranked by number of search terms found in the full patent.
  • Filters can be applied for classification codes or parts of patents.
  • The report now gives primary CPC classification, assignee and title in addition to the patent number and date of publication, now together with abstract and first claim.
  • Comparison of each matched patent with the search document.
  • Parallel display of the matched sentences, with location in the patent identified (Abstract, Brief Summary, Claims, Description).
  • Automatic collection of the citations for each matched patent.
  • Ability to compare any of the citations with the search description, or the citing patent, with parallel display of the results as for patents.
  • Comparative vocabulary use for each comparison pair.
  • Unified operation across US and EPO  and WIPO datasets.
  • Searching in original languages, including Chinese.
