In my patent searches, I have found some patents with upwards of 300 claims. This has me impressed. I'm wondering what the world record for the greatest number of claims in any patent is. Does anyone know the patent that holds this record?

I am not sure there is an official world record, but doing a quick search using AcclaimIP, here are the top 3*:

  1. 887: US6684189 Apparatus and method using front-end network gateways and search criteria for efficient quoting at a remote location

  2. 868: US5095054 Polymer compositions containing destructurized starch

  3. 803: US7096160 System and method for measuring and monitoring wireless network performance in campus and indoor environments

*Granted patents, US/JP/EP/DE

It's worth noting that this is a patent application and not a granted patent, as the question is asking for. I've formatted this answer a bit, and specifically indicated that fact in the header. – Matthew Haugen Jun 18 '15 at 23:33
