Patent searching tips
Approximately 80% of patents contain information published nowhere else, but patents can be very difficult to find. In fact, some patents are deliberately designed to be hard to retrieve in a patent search.
In addition, names used in patents may change over time, and the owner of the patent, or assignee, may change as well.
Try following these tips when beginning a patent search:
- Find as much information as you can about the drug: alternate names, patent holder, and approximate dates
- Try a keyword search for the most common names, combined with the patent holder as assignee
- Make use of the patent citations
