One common confusion people have when reading patent is the word "comprise," which appears a lot in the claim language. This probably comes from the confusing definition of the word in the legal dictionary, http://legal-dictionary.thefreedictionary.com/comprise http://legal-dictionary.thefreedictionary.com/comprise, which implies there are more elements than the ones specified.
Comprise always means all or nothing in the claim conditions. All conditions have to be satisfied for the claim to be valid against a product.
- jballer 12y ago"Comprising" means having at least all of the listed elements. "Consisting of" means having all of the listed elements and nothing more. "Consisting essentially of" means having all of the listed elements, with more stuff that doesn't materially change the character of the invention (that's where the lawyers come in). http://www.uspto.gov/web/offices/pac/mpep/s2111.html http://www.uspto.gov/web/offices/pac/mpep/s2111.html
