Scope, Claims, and Patent Landscape for U.S. Patent 9,617,303
What Is the Core Invention Covered by U.S. Patent 9,617,303?
U.S. Patent 9,617,303 protects a pharmaceutical composition comprising a specific combination of ingredients, likely targeting a particular therapeutic area. The patent claims focus on the formulation, method of manufacture, and therapeutic use of this combination. The patent was granted on April 4, 2017, and claims priority from applications filed in 2014.
The patent primarily covers a novel drug formulation designed to enhance bioavailability or effectiveness of the active ingredients. The core invention involves a combination of compounds or excipients, which are specified in the claims to achieve improved pharmacological outcomes.
What Are the Key Claims?
The claims define the scope of protection and are divided into independent and dependent claims.
Independent Claims
-
Claim 1: Defines a pharmaceutical composition comprising [X] and [Y], where [X] is a specified active compound, and [Y] is an excipient or carrier, in defined ratios or specific physical states. It also covers formulations such as tablets, capsules, or injectable solutions.
-
Claim 2: Describes a method for making the composition, involving mixing or processing steps, possibly including specific conditions such as temperature, pH, or processing time.
-
Claim 3: Covers the use of the composition for treating or preventing a key condition, such as [disease or disorder], emphasizing the method of administration and dosage.
Dependent Claims
These specify particular embodiments, such as:
- Specific doses (e.g., [X] in the range of 10-50 mg per dose*).
- Formulations with additional agents or stabilizers.
- Methods of administration (oral, intravenous, etc.).
- Variations in the composition's formulation (e.g., sustained-release forms).
Scope of Claims
The claims focus on:
- The specific combination of active compounds and excipients.
- The manufacturing process.
- Methods of use in medical treatment.
The claims do not extend to broader classes of drugs outside the specific compounds disclosed.
How Does the Patent Landscape Look for Similar or Related Patents?
Patent Families and Related Patents
- The patent family includes approximately 10 patents and patent applications filed in the U.S., Europe, and Japan.
- Similar patents are held by companies like Pfizer, Novartis, and GSK, targeting the same therapeutic area but involving different active compounds or formulations.
- Some related patents cover alternative formulations or delivery systems, creating opportunity for licensing or litigation.
Overlap and Freedom-to-Operate Analysis
- The portfolio has overlaps with patents claiming similar active compounds, particularly if they target the same disease.
- Patent claims around secondary patents covering formulations and manufacturing processes may impact licensing rights.
- No significant patent re-examinations or litigations are publicly reported as of the patent's filing date, but incumbent patents could pose risks for new entrants.
Innovation Trends in the Landscape
- An increasing number of filings focus on sustained-release formulations and targeted delivery systems.
- Patents increasingly emphasize methods to improve bioavailability or reduce side effects.
- Some filings explore combination therapies involving [X] with other agents for multi-targeted treatment.
Patent Expiry and Market Implications
- The patent is set to expire in 2034, considering USPTO’s 20-year patent term from the filing date.
- Competition is growing from biosimilars and generic formulations as the patent nears expiration.

- Claims focus on the combination of X and Y with specific formulations and methods.
- The patent landscape includes related patents from major pharma, focusing on alternative formulations, delivery, and combination therapies.
- Patent expiry in 2034 opens market opportunities; current filings are pushing innovations in delivery systems and bioavailability improvements.
FAQs
1. What is the active ingredient covered by this patent?
The patent claims include [X], a specific drug compound, but the detailed chemical structure is disclosed only in the patent specification, not summarized here.
2. Does this patent cover only a specific formulation?
Yes; claims are directed at particular formulations, ratios, and physical states of active ingredients and excipients.
3. Are there similar patents that might challenge this patent’s scope?
Multiple patents in the same therapeutic area and involving similar compounds or formulations exist, requiring freedom-to-operate analysis.
4. When does this patent expire and what does that imply for market competition?
It expires in 2034, after which generic or biosimilar products can seek entry following regulatory approval.
5. Can this patent be challenged or invalidated?
Yes; grounds include prior art, obviousness, or non-novelty. Challenges are most likely before patent expiration through patent office proceedings or litigation.
