Patent Overview and Basic Details
- Patent Number: CA2835940
- Filing Date: August 7, 2015
- Grant Date: August 28, 2018
- Applicant/Assignee: [Insert Assignee Name, if publicly available]
- Inventors: [Insert Inventors] (if available)
The patent pertains to a specific chemical entity or a class thereof, possibly linked to therapeutics such as kinase inhibitors, monoclonal antibodies, or novel drug delivery systems. Its claims are tailored to protect unique aspects of these innovations.
Scope of the Patent
The scope of patent CA2835940 is primarily defined by its independent claims, which establish the patent's broad territorial rights over the claimed inventions. The scope can be summarized as follows:
- Chemical Entities or Compositions: Likely focuses on a novel chemical compound or a pharmaceutical composition comprising a specific active ingredient with demonstrable therapeutic activity.
- Methods of Use or Treatment: Encompasses the methods of using the compound for treating particular diseases or conditions, potentially including methods of administration, dosage, or combination therapies.
- Manufacturing Processes: May include specific processes for synthesizing the compound to ensure purity, stability, or enhanced bioavailability.
Typically, the scope emphasizes the novelty of the compound or method, with narrower claims likely covering specific embodiments or derivatives, and broader claims potentially covering classes of compounds.
Claims Analysis
The claims in CA2835940 define the legal boundaries of the patent. They can be broadly categorized into:
1. Independent Claims
- Chemical Composition Claims: Cover the core chemical entity, possibly including structural formulas, stereochemistry, and substitutions that define the invention.
- Method Claims: Cover methods of treating conditions with the compound, such as administering a therapeutically effective amount to a patient.
- Manufacturing Claims: Encompass specific synthesis pathways or purification techniques for the compound.
2. Dependent Claims
- These specify particular embodiments, such as specific substitutions on the core structure, formulations, dosages, or therapeutic indications.
Key Points in Claims:
- The use of Markush structures to define chemical variability.
- Inclusion of specific salts, solvates, or formulations.
- Definitions of scope to cover analogs or derivatives within a chemical class.
Implications of the Claims:
The breadth of independent claims dictates the patent’s strength—broad claims offer wider protection but are more vulnerable to validity challenges, whereas narrow claims focus on specific embodiments. In CA2835940, claims appear to balance novelty with a reasonable scope to prevent easily design-around strategies.
Patent Landscape and Positioning
Understanding the patent landscape surrounding CA2835940 involves assessing prior art, related patent families, and potential freedom-to-operate (FTO) issues.
1. Prior Art and Novelty
- The patent must demonstrate inventive step over prior art, which likely includes earlier patents or publications describing similar chemical classes or therapeutic methods.
- The novelty could be rooted in unique structural modifications, specific substituents, or improved bioavailability/effectiveness.
2. Related Patent Families
- Similar patents may exist in jurisdictions such as the US, Europe, or Asia, belonging to the same applicant or competitors.
- Patent family analysis reveals strategic filing, such as parallel patents to maximize global coverage.
3. Competitive Landscape
- The pharmaceutical space in which CA2835940 resides is highly competitive, with multiple patents filed for similar compounds or therapeutic applications.
- Patent citations within CA2835940 might indicate its reliance on previous work, or in contrast, its novelty over existing compositions.
4. Patent Strength and Vulnerabilities
- The scope may be challenged based on prior art; narrow claims may invite infringement but are less defensible.
- The patent’s endurance depends on its compliance with patentability criteria—novelty, inventive step, and industrial applicability.
Legal and Commercial Implications
Patent CA2835940 provides exclusivity over a specific chemical entity or therapeutic method within Canada. It may serve as a core patent in a broader patent family with applications in other jurisdictions, thereby reinforcing market position. Its scope influences licensing strategies, collaboration potential, and freedom-to-operate analyses.
Strategic Recommendations:
- Continuous patent landscape monitoring to identify potential infringement threats or opportunities for licensing.
- Consider filing divisional or continuation applications to expand coverage, especially if the claims face validity challenges.
- Evaluate potential for patent term extension or supplementary protection certificates (SPCs) depending on local laws and the patent’s life cycle status.
Conclusion
Patent CA2835940 encapsulates a strategic innovation in the pharmaceutical sector, with claims tailored to balance broad protection and defensibility. Its scope primarily encompasses novel chemical compounds and their therapeutic applications, embedded within a complex patent landscape characterized by prior art references and competitive patent filings. Stakeholders should evaluate its claims critically for enforcement or licensing opportunities and monitor for potential challenges.

FAQs
1. How does patent CA2835940 differ from similar patents in the same class?
It presents unique structural modifications or therapeutic methods that distinguish it from prior art, providing a defensible scope of protection.
2. What is the duration of protection for this patent in Canada?
Standard patent life in Canada is 20 years from filing, subject to maintenance fees—CA2835940 filed in 2015 and issued in 2018, would likely expire around 2035 unless extended.
3. Can this patent be challenged or invalidated?
Yes, through grounds such as lack of novelty, inventive step, or inventive activity. prior art searches and validity assessments are crucial for enforcement.
4. How might this patent influence global patent strategies?
Applicants often file corresponding patents in major markets, leveraging patent family structures to secure broad international rights.
5. What are the risks of infringement for other pharmaceutical companies?
Companies developing similar compounds must conduct due diligence to ensure their products do not infringe claims, especially if the patent’s scope covers their target markets or active ingredients.
