Hi all,
I want to access the sequence listing of a certain patent. However, it seems that there is no direct way to access the file referenced in the patent.
How do I proceed in such a case?
Thanks in advance.
Cheers,
Michael
These files are usaually acessible only through the respective patent office page (USPTO, EPO, WIPO). Access the patent from there and look for something like "Documents". Your file is probably hiding there.
I can check the file for you if you send me the patent number.
It is difficult to find a free reliable sequence search tool. Most of the commercial patent providers have a sequence search feature incorporated in their databases, like e.g. STN http://www.stn-international.com/sequence_searching.html. Patent offices require to file sequences in a certain format, often in .pdf, which makes it difficult for a flexible search. However, Espacenet offers a search 'full text' in their PCT/EP collections with sequences: https://worldwide.espacenet.com/advancedSearch?AP=&CPC=&DB=en.worldwide.espacenet.com&EXTFTXT=%22TTT+GACCGGCAGTTT+AT+GAT+AAT+CT+CACCAGCAGT+AGAT+ACTT+AT%22&IC=&IN=&PA=&PD=&PN=&PR=&REF=yes&ST=advanced&locale=en_EP
This sequence will be highlighted in the description. Be aware that also two-letter combinations are indicated. Another source is patentscope from WIPO: https://patentscope.wipo.int/search/en/structuredSearch.jsf. You can search in the English description with the saame equence as in Espacenet and you'll find the same result. Still another source is https://www.lens.org/lens/bio/patseqfinder/view#input
So, when you talk about a particular patent, with the publication number, you'll should find the sequence in the description or as a drawing. Good luck
You can use freepatentsonline.com and just enter your sequence into the Search filed as in the example attached. This works especially If you expect just a few hits, i.e. your sequence is relatively rare. On the other hand, if you have hundreds of hits, it is easier to work with professional databases like STN. I've worked with relatively frequent DNA sequences and I dad sometimes hundreds of hits with some documents listing tens of thousands sequences.
