Comparison of Patentsview's api and Pair Bulk Data's api

Here's a summary of the differences I've noticed between Patentsview's and Pair Bulk Data's apis. My pages about the pair bulk api are here.

Is Document Identifier returned by the api? data ex. US 20160066296 A1NoYes!


¹uspc/ccl's remain for design and plant patents as well as reissues of either.
²The aggregating of counts, disambiguation and geo coding makes it look like it will be hard to keep up with the weekly issuing of patents. Data loads don't appear to be incremental and are supposed to occur quarterly.

Use case 1

I'd like to programmatically retrieve a few fields for the plant patents issued each Tuesday. I can't use the patentsview api since its data lags behind/doesn't seem to get updated with any regularity. I could use the Pair Bulk Data api but it only returns one uspc classification (aka ccl) per patent when multiples are allowed, it's not returning cpcs that are now coming back on some plant patents, and it sometimes returns a non existent classification of PLT/999.999. See my plant patents page here.

Use case 2

I'd like to be able to match up applications of a particular company (as the assignee) to their subsequent patents, if they were issued. http://appft.uspto.gov/ will return the Document Identifier and title for the applications via a search for an/"Comany Name". Pairbulk doesn't offer assignee as a searchable field and the First Named Appliccant does not return all of the assigned patents. Patentview doesn't return the Document Identifier so I can't use the patentsview assignee endpoint's data to match up the issued patent's Document Identifier returned by appft (up to 50 results per page). To satisfy this use case I'd like to see Pairbulk add an assignee search, patentsview return Document Identifier and for someone to stand up an api that returns application data!
