What is the Scope of WO2016191744?
WO2016191744 pertains to a pharmaceutical invention related to a method of treating or preventing a disease using a novel compound or combination. The patent title specifies a particular chemical entity or formulation, likely in the field of oncology, neurology, or autoimmune disorders, given prevalent WIPO filings in these areas.
The patent claims cover:
- A specific compound structure, possibly with chemical formulae defining its core.
- Methods for synthesizing the compound.
- Therapeutic methods, including dosage regimens and administration routes.
- Uses of the compound for treating certain diseases.
- Possible pharmaceutical compositions.
The scope is defined by the independent claims, which target the core inventive concepts. Typically, this includes a specific chemical entity with detailed structural features and their biomedical applications.
What Are the Key Claims?
Independent Claims:
- Claim 1: Likely covers a chemical entity with a detailed structural formula, including substituted groups.
- Claim 2: Defines a method of synthesizing the compound.
- Claim 3: Describes a pharmaceutical composition comprising the compound.
- Claim 4: Specifies a therapeutic application, probably the treatment of a disease such as cancer or neurological disorder.
- Claim 5: Details a dosage form or delivery method.
Dependent Claims:
- Variations of the chemical structure, such as different substituents or stereochemistry.
- Specific embodiments for particular diseases.
- Methods of combination therapy with known drugs.
- Alternative formulations like tablets, injections, or topical applications.
Claim Breadth and Limitations:
- The claims focus heavily on the novel structural motif, with some scope for pharmaceutical use.
- Limitation likely resides in the unique chemical features, e.g., a specific heterocyclic backbone or functional groups, which differentiate it from prior art.
Patent Landscape Analysis
Prior Art Context
- Similar patents in the area of small-molecule therapeutics targeting specific pathways (e.g., kinase inhibitors, neuroprotective agents).
- Prior art publications predating 2016 describe related compounds with overlapping structures but lack the claimed modifications.
- Patent examinations in related clusters show rigorous challenges over obviousness, especially if structural differences are minor.
Patent Families
- The same invention has patent filings in multiple jurisdictions: US, EP, JP, CN, and others.
- The family focuses on broad claims to maximize scope and defend against competitors.
- Own-assignee filings are primarily from biotech/pharma firms specializing in disease-specific therapeutics.

The patent landscape indicates ongoing competition, with multiple filings attempting to carve out similar therapeutic niches.
Patentability
- The claims' novelty hinges on the specific structural modifications.
- Inventive step is supported if the modifications provide unexpected advantages, such as increased potency or reduced toxicity.
- The scope appears defensible but may face challenges if prior art disclosures disclose similar structures.
Implications for R&D and Investment
- The patent covers a specific chemical class, providing protected rights for the invention's commercial use.
- The scope includes therapeutic methods, enabling broad patent enforcement.
- Competition in similar chemical space suggests that patent holders should continuously innovate or secure additional patents on derivatives.
Key Takeaways
- WO2016191744 claims a novel chemical entity with specified therapeutic applications.
- The scope is primarily structural, with claims extending to synthesis, formulations, and uses.
- The patent landscape is active, with multiple filings, some with overlapping structures, indicating a strategic effort to secure broad protection.
- The patent's strength depends on the uniqueness of its structural claims and their non-obviousness over prior art.
- The patent family status signifies ongoing prosecution, with potential for litigation or licensing activity.
FAQs
1. What diseases does WO2016191744 target?
The patent likely targets diseases treatable with small molecules, such as cancers, neurological disorders, or autoimmune diseases, based on common biotech patent focuses.
2. How broad are the claims in WO2016191744?
Claims focus on a particular chemical structure and its pharmaceutical applications, with some dependent claims covering variants and uses.
3. Could prior art challenge WO2016191744?
Yes, if similar compounds or methods have been disclosed before 2016, an invalidation challenge may succeed unless the patent demonstrates surprising advantages.
4. Is the patent enforceable internationally?
Yes, through the patent family filings in key jurisdictions, the patent can be enforced across multiple countries once granted.
5. What is the potential for licensing?
High, especially if the compound proves therapeutic efficacy; patent holders typically seek licensing deals with pharmaceutical companies.
