DEFINITION

Classification: 514/772.3

Solid synthetic organic polymer:

(under subclass 772) Subject matter wherein the designated

organic nonactive ingredient is a solid synthetic polymer, e.g., a pharmaceutical preparation containing a bio-degradable polymer derived from a monomer mixture comprising 2, 2-bis (epsilon-caprolactone-4-yl) propane, gamma-valerolactone and epsilon-caprolactone, etc.

SEE OR SEARCH THIS CLASS, SUBCLASS:

78.01+, for a pharmaceutical composition which contains a solid synthetic organic polymer which functions as a designated organic active ingredient.

78.08, for a more thorough discussion on polymers which are proper for Classes 424, 514, and Class 520 Series.
