Do patents provide critical incentives to encourage investment in innovation? Or, instead, do patents impose legal risks and burdens on innovators that discourage innovation, as some critics now claim? This paper reviews empirical economic evidence on how well patents perform as a property system. Do Patents Perform Like Property? 1

Alkyldifluorophosphites, ROPF2 (R = ^-substituted benzyl group, neopentyl, 1-adamantyl) have been obtained by a new method, involving reaction of the appropriate alkyl trimethylsilylether, ROSiMe3 with chlorodifluorophosphine, PF2C1. Reactions of these difluorophosphites with platinum(II) complexes of the type [LaPtCla] (L = PEt3, PPI13) led to products such as irans-[L2PtCl(POF2)] and {[p-XC6H...

Myelofibrosis is reported in patents with primary hyperparathyroidism. It is also was reported in patents with sec- ondary hyperparathyroidism due to end-stage renal disease or Vitamin D dependent rickets .We present a case of celiac disease and osteomalacia which leads to secondary hyperparathyroidism and myelofibrosis.

Studies on models synthesized by stereochemically controlled routes show that the central triene chromophore in the common cis isomer of phytoene has the irans,cis,trans configuration, and that the phytoene from Flavobacterium dehydrogenans consists mainly of the all-trans isomer. Capsorubin, with the natural configuration at all four chiral centres, has been synthesized from (+)-camphor. Sever...

In this Article, we propose a way to improve the workings of the patent system. Unlike most extant reform proposals that focus on the USPTO and the Federal Circuit and the procedures they employ, our proposal is conceptual in nature. We introduce two new intellectual property forms—“quasipatents” and “semi-patents.” Both forms are designed to mitigate the social costs of traditional patents by ...
