Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
54 words
A method of making demineralized bone particles which comprises demineralizing whole bone and thereafter subdividing the demineralized bone into demineralized bone particles, wherein subdividing of the demineralized bone is carried out by applying pressure to the demineralized bone using a mechanical press, wherein the pressure is applied from about 1,000 to about 40,000 psi.
Claim 2
Independent Claim
54 words
A method of making demineralized bone particles which comprises demineralizing whole bone and thereafter subdividing the demineralized bone into demineralized bone particles, wherein subdividing of the demineralized bone is carried out by applying pressure to the demineralized bone using a mechanical press, wherein the pressure is applied from about 1,000 to about 40,000 psi.
Claim 3
Dependent Claim
14 words
The method of claim 1 wherein the bone is subjected to pressing while unconstrained.
Claim 4
Dependent Claim
18 words
The method of claim 2 wherein the product of pressing is subjected to an additional pressing while constrained.
Claim 5
Dependent Claim
14 words
The method of claim 1 wherein the bone is subjected to pressing while constrained.
Claim 6
Dependent Claim
17 words
The method of claim 1 wherein the product of pressing is subjected to an additional subdividing operation.
Claim 7
Independent Claim
54 words
A method of making demineralized bone particles which comprises demineralizing whole bone and thereafter subdividing the demineralized bone into demineralized bone particles, wherein subdividing of the demineralized bone is carried out by applying pressure to the demineralized bone using a mechanical press, wherein the pressure is applied from about 5,000 to about 20,000 psi.
Claim 8
Independent Claim
54 words
A method of making demineralized bone particles which comprises demineralizing whole bone and thereafter subdividing the demineralized bone into demineralized bone particles, wherein subdividing of the demineralized bone is carried out by applying pressure to the demineralized bone using a mechanical press, wherein the pressure is applied from about 5,000 to about 20,000 psi.
Claim 9
Dependent Claim
14 words
The method of claim 6 wherein the bone is subjected to pressing while unconstrained.
Claim 10
Dependent Claim
18 words
The method of claim 7 wherein the product of pressing is subjected to an additional pressing while constrained.
Claim 11
Dependent Claim
14 words
The method of claim 6 wherein the bone is subjected to pressing while constrained.
Claim 12
Dependent Claim
17 words
The method of claim 6 wherein the product of pressing is subjected to an additional subdividing operation.
