Inventing Around Edison’S Lamp Patent: The Role Of Patents In Stimulating Downstream Development And Competition, Ron D. Katznelson, John Howells
Inventing Around Edison’S Lamp Patent: The Role Of Patents In Stimulating Downstream Development And Competition, Ron D. Katznelson, John Howells
Ron D. Katznelson
We provide the first detailed empirical study of inventing around patent claims. The enforcement of Edison’s incandescent lamp patent in 1891-1894 stimulated a surge of patenting. Most of these later patents disclosed inventions around the Edison patent. Some of these patents introduced important new technology in their own right and became prior art for new fields, indicating that invention around patents contributes to dynamic efficiency. Contrary to widespread contemporary understanding, the Edison lamp patent did not suppress technological advance in electric lighting. The market position of General Electric (“GE”), the Edison patent-owner, weakened through the period of this patent’s enforcement.

Bad Science In Search Of “Bad” Patents, Ron D. Katznelson
Bad Science In Search Of “Bad” Patents, Ron D. Katznelson
Ron D. Katznelson
This paper draws attention to fundamental deficiencies in studies that have been relied upon as authoritative sources on patent grant rate comparisons among national patent offices. The two prominent studies analyzed here had employed erroneous methods to compare patent grant rates, resulting in false high indications of such rates at the U.S. patent office compared to foreign patent offices. The three identified categories of analysis errors found in these studies were (i) the misapplication of conditional probability; (ii) miscounting invention applications; and (iii) failure to account for patent obsolescence and application attrition due to the widely differing delays among national …
