In poldham/lensr: Access the Lens Patent Database

Description Usage Arguments Details Value Examples

Search the Lens using individual or combinations of IPC Codes. Note this function is experimental. IPC based searching is not convincing in the Lens at present (for example try entering medical preparation into the full text search field and the code A61K subclass (for medical preparations) and the result is 79). Further investigation and clarification is required.

1	lens_ipcs(ipc, ipc_boolean = "NULL")

`ipc`	An ipc code or vector of codes (character)
`ipc_boolean`	"AND" or "OR" (quoted)

IPC codes on the group level must include a forward slash e.g. A61K31/00 or C12N15/82 or the Lens will not display results. A forward slash is not necessary on the subclass level e.g. A61K or C12N.
