DECISION ON APPEAL
This appeal involves claims to cementitious mixtures containing polyelectrolytes,
and methods of making the mixtures. The examiner has rejected the claims as
anticipated or obvious. We have jurisdiction under 35 U.S.C. § 134. We reverse.
Background
“Portland cement is one of the most widely used materials in the construction
industry. . . . For example, conventional ‘concrete’ is a cementitious mixture comprising
portland cement, water and aggregate, such as sand or a mixture of sand with
gravel. . . . The cement is the matrix that, when mixed with water, hardens and bonds
the aggregate particles into a rigid solid.” Specification, page 1.
