CAMBIA's Sequence Project in Patentlens is now replaced by PatSeq Finder in the Lens (www.lens.org)

Now you can search and analyze the protein and DNA sequences listed in patents and patent applications from 15 jurisdictions, and specifically search sequences in claims, using bioinformatics tools such as NCBI's BLAST

Check out PatSeq Finder

We are now able to offer filters by organism name, and we welcome collaboration to develop searchable maps of patent sequences on specific genomes through the Lens project. 

Sequence listings have been mostly available from patent offices as pdfs or images in a patent document, i.e. not searchable.  in the past few years, Cambia developed an extensive patent sequence searchable database, and delineated which sequences are actually mentioned where in the text of a patent document, especially in the claims section of a patent.

For any reference of the biological Lens, the user should properly cite the data in any publication or in the metadata, in the following form:

Osmat A Jefferson, Deniz KoĢˆllhofer, Thomas H Ehrich & Richard A Jefferson 2013. Transparency tools in gene patenting for informing policy and practice. Nature Biotechnology, volume 31, No. 12, p 1086 – 1093,

  • You may be surprised to know that until CAMBIA did this work starting in June 2006, there wasn't a publicly available cost-free listing, in searchable form, of the biological sequences listed in US patent applications!  
  • Cambia also developed a method to delineate which sequences are actually mentioned in the claims of granted patents or patent applications. 

We've supplied the information on the sequences in patent applications, and in claims, to Genbank, which is also working with the USPTO.  Genbank sequences can now link to the relevant patent application documents in both the USPTO database and the Patent Lens, as currently happens for US granted patent documents.  

An advantage of the link to the patent documents on the Lens, in addition to downloadable pdfs the USPTO does not supply, is that entries are also linked to information on the status of related patents and applications in other countries that report this information.  Since many of these countries do not provide searchable databases to the general public, this may be the only notification the public has about pending gene sequence applications in these countries.  We welcome collaboration to explore this dataset further, to extend to sequence listings submitted in patent applications to many other jurisdictions, for example.
