IBM Patents and Defensive Publishing
According to a press release by IFI Patent Intelligence, IBM continued in 2007 as the top corporate assignee of granted patents, as it has for the previous 14 years, with 3,148 patents, down more than 500 grants from the previous year.
But the number of patents granted to IBM represents just a fraction of the many thousands of innovations documented each year by the company. How then, if not by patent application, does IBM secure its innovations for potential future patents or implementation?
Defensive publishing. Here are a few examples of interesting innovations recently published by IBM in the IP.com Prior Art Database:
- A device to warn inattentive drivers they are approaching a red traffic light
- A Methodology for Providing Spa Services in a Virtual World
- Method to ensure timely response to email messages by using probability derived from past interactions
