IBM Master Inventor
An IBM Master Inventor is an individual selected by IBM. The qualification and appointment to Master Inventor is governed by the value to IBM of an inventor's contribution to the patent portfolio, and through defensive publication (published in www.ip.com). IBM weighs many aspects of an inventor's contributions, including but not limited to impact of invention through licensing, inclusion in product, and percentage of patents with a measurable impact. IBM also considers an individual's contribution to the inventing community inside IBM, whether by acting as a patent reviewer, or providing feedback and guidance to new inventors.
IBM Master Inventors are appointed to two to three year terms, which are sometimes renewed. They are expected to identify new inventions, mentor other employees through the patent process, foster innovative thinking, and help evaluate ideas for patenting. Becoming a Master Inventor is the result of a cumulative contribution to the IBM patent portfolio. According to one Master Inventor  the citation reads:
|“||Each year, IBM asks a small group of employees to join the ranks of Master Inventor. This group of people is asked to assist in the identification of new inventions and mentor others in the use of the patent process, among other things. The invitation to become a Master Inventor is based on the value to IBM of an inventors' United States patents during the three prior calendar years. This achievement is significant because it is the result of a cumulative contribution to the IBM patent portfolio, including Corporate Patent Portfolio Awards, Division Patent Portfolio Awards, and Division Supplemental Patent Issuance Awards.||”|
