Meaning and Interpretation of Chemical Patents

The subject of chemical patents is introduced by considering the structure of the patent specification, the terminology peculiar to patents in chemical and nonchemical fields, and the effect of these factors upon validity. Also, requirements for disclosure in the specification of chemical patents are discussed, including the showing needed to establish utility, especially with regard to patents on drugs. To illustrate the importance of some of these matters when it comes to a suit on the patent, such a suit is followed through the trial and appeal courts up to and including the U. S. Supreme Court, with a discussion of some other aspects of the patent law that are brought out in the suit.
