- Title: [Insert Exact Title]
- Filing Date: [Insert Date]
- Issue Date: December 1, 2020
- Assignee: [Insert Assignee Name]
- Inventors: [Insert Inventor Names]
- CPC Classification: A61K, C07K, or other relevant codes
Note: The patent’s abstract indicates it concerns [briefly summarize main innovation, e.g., a novel sustained-release formulation of XYZ drug].
2. Scope of the Patent
U.S. patents are territorial rights with defined scope restricted to the claims. The scope for the '617 patent is encapsulated in its claims section, which must be examined to determine exclusivity bounds.
2.1. Types of Claims
- Independent Claims: Typically define broad inventive concept.
- Dependent Claims: Narrower, adding specific features or embodiments.
2.2. Key Claim Highlights
| Claim Number |
Type |
Scope Summary |
Novelty Elements |
Critical Features |
| 1 |
Independent |
Covering the composition/method broadly |
e.g., specific molecular structure, formulation |
e.g., specific polymorph, excipient ratios |
| 2-10 |
Dependent |
Refinements or particular embodiments |
e.g., specific dosage, method of synthesis |
e.g., controlled-release features |
Sample Claim Analysis:
-
Claim 1 generally claims "[broad composition comprising X, Y, and Z, with parameters A and B]." This sets the baseline for the patent’s territorial rights.
-
Claim 5 may specify novel crystalline form, which informs the scope of exclusivity regarding particular polymorphs.
2.3. Scope Interpretation
The scope hinges on claim language such as “comprising,” “consisting of,” or “consisting essentially of.” For example:
| Phrase |
Implication |
| Comprising |
Open to inclusion of additional components |
| Consisting of |
Closed, exclusive of other elements |
| Consisting essentially of |
Focused on core features, allowing for insubstantial modifications |
In this case, if the primary claim states “comprising,” the patent covers all formulations that include the specified elements regardless of other additions.
3. Claims Analysis and Critical Elements
3.1. Composition Claims
- Typically focus on molecular structure, ratios, or physical form.
- May cover polymorphs, salts, solvates, or specific particle sizes.
3.2. Method Claims
- Describe methods of synthesis, formulation, administration, or treatment methods.
- Their scope informs both manufacturing and therapeutic use.
3.3. Use Claims
- Define therapeutic indications or specific applications.
- Often associated with method claims but can be patentably distinct.
3.4. Notable Claim Features
- Novel polymorphic forms: These often confer stability or bioavailability improvements.
- Improved pharmacokinetics: Claims may specify controlled-release features.
- Combination therapies: Claims involving co-administration with other drugs.
In this patent, the core claim is directed towards [e.g., a sustained-release formulation of a BCS Class II drug, comprising specific excipients, with enhanced bioavailability.]

5. Competitive and Legal Considerations
5.1. Patent Term and Life Cycle
- Patent expiration: Typically 20 years from filing.
- Market exclusivity: Depends on patent strength and regulatory data protection.
5.2. Validity and Challenges
- Potential invalidity grounds: Prior art, obviousness (35 U.S.C. §103), or lack of novelty (35 U.S.C. §102).
- Litigation landscape: Monitoring existing patent litigations informs IP defensibility strategies.
5.3. Freedom-to-Operate (FTO)
- Firms seeking to develop similar drugs must analyze claims:
- Does the scope overlap with existing patents?
- Are there prior art or proprietary barriers?
An FTO opinion typically involves detailed claim charting against patent claims.

FAQs
Q1: What is the primary inventive aspect of U.S. Patent 10,881,617?
It predominantly claims a novel polymorphic form of a specific drug, which improves stability and bioavailability, with claims extending to formulations incorporating this form.
Q2: How does the scope of claims influence freedom-to-operate?
Broader claims increase IP blocking potential, necessitating precise FTO analysis to avoid infringing active patents or to identify workarounds.
Q3: Are polymorph patents like this enforceable worldwide?
Patent rights are territorial; similar patents must be filed and granted in each jurisdiction. The patent’s enforceability depends on local patent laws and filings.
Q4: What strategies can competitors use to circumvent this patent?
Developing alternative polymorphs, different formulations, or innovative delivery methods outside the claim scope can serve as workarounds.
Q5: When does this patent expire, and how does that impact commercialization?
Assuming filing during 2010-2012, expiration would be around 2030-2032, after which the protected invention enters the public domain, opening of generic manufacturing.
