Copyright check

I quickly checked this page and found that a fragment of text starting from The GIC channels are divided into three types: (1) a-amino-3-hydroxy-5-n ethyl-4- isoxazole propionate (AMPA)- was indeed copied, however it was copied not from the patent, but from the corresponding TCDB entry (this user uses TCDB abstracts). Both the patent and the TCDB entry contain the same text. Given that TCDB exists for a very long time, well known, and is under free reuse license, I would think that authors of the patent copy-pasted this text from TCDB, without providing appropriate attribution. The same could be with some other alleged copyright violations by this user. Now, let's compare the patent with another TCDB entry [1]. Both include same text (each with N- and C-termini on the inside of the cell, two amphipathic transmembrane spanning segments...) in another paragraph. Note that both paragraphs in patent which reuse texts from TCDB do not contain any references, whereas other paragraphs in the patent contain references. If this is a copyright violation, it was made by authors of the patent. My very best wishes (talk) 16:16, 24 April 2016 (UTC)[reply]

Copyright problem removed

Prior content in this article duplicated one or more previously published sources. The material was copied from: http://www.google.com/patents/WO2002026805A2?cl=en,_dated_26_September_2001. Copied or closely paraphrased material has been rewritten or removed and must not be restored, unless it is duly released under a compatible license.

Note: the patent is dated 26 September 2001; tcdb.org was registered on 10 June 2004. Justlettersandnumbers (talk) 14:23, 7 February 2017 (UTC)[reply]

I believe the text of US patents is typically in the public domain (see Copyright on the content of patents and in the context of patent prosecution). However Googling sentence fragments strongly suggests to me that large parts of the text in the article was copied from earlier sources, e.g. this 1999 book, so I've deleted it on that basis.
