DEFINITION
Classification: 264/36.11
Articles containing nontextile porous material (e.g., foam, sponge, etc.):
(under subclass 36.1) Processes, wherein the article to be renewed or reconditioned contains randomly dispersed pores or voids and contains no textile.
(1) Note. Acceptable for this subclass are composite-structured articles wherein one article section may be porous while another article section is nonporous.
(2) Note. Utilizing putty to repair wooden articles for reuse is properly classified in this subclass since wood is considered to be inherently porous.
