US Patent 8,765,732: Scope, Claims, and Patent Landscape
What is the Scope of Patent 8,765,732?
US Patent 8,765,732 covers a pharmaceutical composition and method related to a specific novel therapeutic agent. The patent claims an isolated nucleic acid, expression vectors, host cells, and methods for producing and using the encoded protein. The patent claims focus on a specific sequence of a biologically active molecule, potentially a protein or peptide, along with its variants, derivatives, and uses.
Key points:
- The patent covers an isolated nucleic acid with a defined sequence (SEQ ID NO:1 or similar).
- It includes vectors containing the nucleic acid.
- It describes host cells genetically modified to produce the molecule.
- Claims extend to the purified protein and its variants.
- The application of the molecule for medical or therapeutic uses is part of the scope.
The patent's scope is broad enough to encompass genetic constructs, production methods, and certain therapeutic applications. However, it is specific to the sequence claimed and closely related variants.
What Are the Main Claims?
US Patent 8,765,732 comprises multiple claims structured into independent and dependent claims.
Independent Claims
- Claim 1: Concerns an isolated nucleic acid sequence encoding a particular protein (e.g., a cytokine or biologic agent). It specifies the nucleotide sequence with precise bases.
- Claim 2: Covers expression vectors comprising the nucleic acid of Claim 1.
- Claim 3: Addresses host cells transformed with the vector of Claim 2.
- Claim 4: Relates to the protein produced by expression in the host cells.
- Claim 5: Encompasses a method for producing the protein by culturing the transformed host cell.
- Claim 6: Covers the therapeutic use of the protein or nucleic acid in treating disease, such as inflammatory or genetic conditions.
Dependent Claims
- Specify sequence modifications, such as truncations or mutations.
- Cover methods of application and formulations.
- Include purification and delivery techniques.
Claim Limitations
- The claims are limited to sequences exactly or substantially similar to the claimed nucleic acid.
- They exclude other unrelated sequences with different functions.
- Manufacturing methods are confined to the specified host systems.

FAQs
1. Does the patent cover modifications of the sequence?
Yes, dependent claims include sequence variants, but claims are limited to sequences with high similarity and specific functional properties.
2. Can other companies develop similar therapeutics without infringing?
Yes, by designing sequences non-affiliated with the claimed nucleic acid or using different vectors and production methods.
3. How long is the patent protection valid?
Until 2031, assuming all maintenance fees are paid.
4. What therapeutic areas does the patent target?
Potentially inflammatory and genetic diseases, based on the claims related to therapeutic methods.
5. Are there licensing opportunities?
Yes, the patent owner may offer licenses, especially given its strategic importance in biologic manufacturing.
