Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 21 words
A process for reducing the particle size of a amorphous protein material which comprises passing the material through a fluid-energy mill.
Claim 2
Dependent Claim 21 words
A process for reducing the particle size of a amorphous protein material which comprises passing the material through a fluid-energy mill.
Claim 3
Dependent Claim 12 words
The process of claim 1 wherein the protein ma­terial is bovine somatotropin.
Claim 4
Dependent Claim 14 words
The process of claim 1 wherein the protein ma­terial is growth hormone releasing factor.
Claim 5
Dependent Claim 42 words
The process of claim 1 wherein the fluid-energy mill is one of the class wherein the fluid energy is admitted in fine high velocity streams at an angle around a portion or all of the periphery of a grinding or classifying chamber.
Claim 6
Dependent Claim 33 words
The process of claim 1 wherein the fluid-energy mill is one of the class wherein fluid streams convey the par­ticles at high velocity into a chamber where two streams impact upon each other.
Claim 7
Dependent Claim 10 words
Milled bovine somatotropin prepared by the pro­cess of claim 1.
Claim 8
Dependent Claim 44 words
A process for formulating a protein material as a parenteral product, which comprises a) reducing the average particle size of the pro­tein material by passing the material through a fluid-energy mill, and (b) admixing the milled material with a pharmacolo­gically acceptable carrier or diluent.
Claim 9
Dependent Claim 44 words
A process for formulating a protein material as a parenteral product, which comprises a) reducing the average particle size of the pro­tein material by passing the material through a fluid-energy mill, and (b) admixing the milled material with a pharmacolo­gically acceptable carrier or diluent.
Claim 10
Dependent Claim 10 words
A parenteral product produced by the process of claim 7.
