Patentability of micro-organisms: Diamond v. Chakrabarty.

Patentability of Stem Cells in the United States.

Until recently, the patentability of stem cells was well established within the judicial and statutory framework in the United States. However, the shifting landscape of patent law, particularly with regard to patent-eligible subject matter under 35 U.S.C. §101, presents new challenges to the patentability of stem cells. In this paper, we discuss the legal precedent that paved the way for stem ...

Who Owns Your Dinner? a Discussion of America’s Patented Genetically Engineered Food

he United States Code provides that “a live human-made micro-organism is patentable,” and further provides for issuance of patents to persons who invent or discover new or useful “manufacture” or “composition of matter;” microorganisms constitute “composition of matter” or “manufacture” within meaning of the code. Thus, since the landmark 1980 Supreme Court case Diamond v. Chakrabarty, thousand...

T HE DECISION rendered by the Supreme Court in Diamond v. Chakrabarty1 allows the new science of biotechnology to come out of the closet and to take its place in the public domain with other scientific achievements that have, for better or for worse, shaped the industrial life of the United States. It is probable that the products which will result from this emerging science will affect each of...

Diamond v. Chakrabarty: oil eaters--alive and patentable.

An Investigation on Two Types of Crystalline Micro-diamond Film Coated Tools Lapping with Sapphire Wafer

Two types of micron-diamond films were prepared on YG6 substrate by hot filament chemical vapor deposition(HFCVD) method. Morphology and orientation of crystalline growth were evaluated by SEM and XRD. Diamond film coated tools and sapphire wafer’ surface before and after lapping experiment  were contrasted. The results indicated that a significant change in Raman spectrum of two types of micro...
