Single value

I've removed the single value constraint as many more complex items will have multiple patents related to them (they should probably be qualified with applies to part (P518)). Thryduulf (talk) 20:28, 15 August 2016 (UTC)

Sure, but than the type of this property is incorrect. This is not an external identifier. Multichill (talk) 19:44, 16 August 2016 (UTC)

How so? Does the external identifier datatype really require a 1:1 correspondence between items and identifiers? If so, why? Thryduulf (talk) 20:56, 16 August 2016 (UTC)

Change Google Patents URL?

Linking to Google Patents seems like a good thing to do, but I'm having trouble with international patents using the current URL format, even when Google has them. The current "http://www.google.com/patents/$1" doesn't seem to work for e.g. http://www.google.com/patents/FR396795; what works is https://patents.google.com/patent/FR396795. US patents seem to work with both URL schemes, e.g. https://www.google.com/patents/US4558302, https://patents.google.com/patent/US4558302. Any objection to changing the URL format to the one that seems to work for more patents? --Joel7687 (talk) 16:40, 22 May 2017 (UTC)

Update: After testing with many more patent numbers, I changed it. --Joel7687 (talk) 15:40, 23 May 2017 (UTC)

For SU patents it would be better to work as follows

http://patents.su/?search=$1&type=number Halfcookie (talk) 00:37, 10 May 2018 (UTC)

• Ah! USSR patents.

"Google Patents" limitation.

You are trying to convert a universal patent number into a non-universal URL. "Google Patents" is not worldwide patent database. Halfcookie (talk) 00:59, 10 May 2018 (UTC)

Can change name from "patent number" to "google patent number"?

This item depends on a google patent record. But there are historic patents from (1) patent offices that no longer exist; (2) letters in the name/number; (3) duplication of patent numbers from one year to the next (UK in 1900-1910 at least). For more see Wikidata:WikiProject Patents. So we need something more flexible in general. But this property is useful for those patents that are on google patents. Maybe we can just change the name to "google patent number". @Halfcookie: What do you think? -- econterms (talk) 13:57, 21 October 2018 (UTC)

• It would be nice if the URL will be generated by a template with follow parameters: 1) the database type (for most links it would probably will be Google database), 2) the patent number, 3) and the optional parameter is a custom link when template has no rule for conversion patent numbers in the URL. Such a template would help to quickly solve the problems with the restructuring of patent web-sites.

if (not custom_URL)
{
switch ( <base type> )
 {
 case "google" : URL = https://patents.google.com/patent/{{{number}}} 
 case "patents_su" : URL = http://patents.su/?search={{{number}}}&type=number 
 case "something_else" : URL = ...
 }
}
else
{
URL = custom_URL
}

Patent holder

Is there a property for inventing or being the assignee of a patent?

Specifically, I wanted to add the details of which patents he invented to the page for Julius Scherzer (Q57833329)。

Thanks,

--DannyS712 (talk) 00:04, 7 December 2018 (UTC)

I'm trying to put good practices here. Feel free to edit that. We don't have anything for assignee yet. For a person, there's inventor (Q205375) to say the person is an inventor. -- econterms (talk) 01:08, 7 December 2018 (UTC)

Request for change to this property

Draft proposal: Let's split the country and patent-number information. This is useful to cover patents from countries that don't have a two-letter abreivation, and more important to cover situations where patent numbers are reused by a country. Steps:

• remove the constraints on the formatting of this item
• add qualifiers for country abbreviation. Usually this will be WIPO ST.3 (P3068): World Intellectual Property Organization standard for the two-letter codes of countries and certain organizations, but sometimes it has to be another kind of country code or abbreviation. Note that some patents were issued by governments that no longer exist, so it's not complete to use only today's WIPO abbreviations.
• add a qualifier for year because sometimes patent numbers are not unique to a country, e.g. Britain before about 1912 restarted each year at number one.

Comments? @Fuzheado: -- econterms (talk) 18:52, 10 March 2019 (UTC)

@Fuzheado: @econterms: definitely needs a qualifier for country; this should be a meta-property pointing to individual national or wipo patent IDs, no? Sj (talk) 16:15, 17 July 2019 (UTC)

Design patents

Is this property meant to accept numbers for design patents? Design patents are similar to normal "utility" patents, except that their identifiers contain a 'D' after the country code, at least as is the case for patents from the United States. Currently, the parameter seems to reject 'D' numbers, but I could have been certain that it would not. FreeMediaKid$ 06:09, 3 September 2022 (UTC)

Cultivar patent number doesn't fit the regex

Here's a patent that I cannot enter on Hydrangea macrophylla 'H2002' (Q113815863) because it doesn't fit the regex: https://patents.google.com/patent/USPP26657P2 If I enter just US26657 that leads to something else entirely. How to fix the property? UWashPrincipalCataloger (talk) 17:36, 7 September 2022 (UTC)

@UWashPrincipalCataloger: Indeed. The admins must allow the regex USPP[0-9]+ for US Plant Patents.--Herrenloses Damenfahrrad (talk) 10:46, 28 February 2023 (UTC)
