[Google Search API] Support `tbm=pts` parameter for patent searches

[marm123]

Currently, we support Images, Local, News, Shopping, and Videos as the tbm parameters. We can also add Patents (pts), which are supported by Google:

Would be also very interested in this feature! Does not seem like a difficult thing to implement, when you have setup other tbm parameters.

@marm123 do you know any timeline regarding this?

And is there a work-around today with the link you provided? For example you have already a Google Scraper, is there a way to instruct the tbm on Google instead of SERP to still get a patent search?

Thank you for any help.

This would be a great feature, I really need it!

[marm123]

@mazzespazze Unfortunately, I can't give you an ETA for implementing this. There is also no workaround to use the tbm=pts in your regular Google Search API calls, as the data is scraped from the different parts of Google, which we do not currently support.

I'll see what I can do about implementing this.

There're two ways to search patents in Google, https://patents.google.com and https://www.google.com/search?tbm=pts. Which do you prefer? @ThomasKinkeldei @mazzespazze @anna-feliz

[ThomasKinkeldei]

I did not do a profound background check but it seems to me that https://patents.google.com/ deliver better results.

[mazzespazze]

@zyc9012 Agree with @ThomasKinkeldei. The site https://patents.google.com delivers better results. But they are also more informative. It shows assignee, inventor, and register. While on the standard Google search, even with the pts parameter, all that is missing.
