Detailed Analysis of Patent CA2822790: Scope, Claims, and Patent Landscape

Last updated: August 8, 2025


Introduction

Patent CA2822790, issued in Canada, pertains to a novel pharmaceutical invention. Analyzing this patent involves understanding its scope, the breadth of its claims, and its landscape within the broader biotech and pharmaceutical patent environment. Such insights assist stakeholders—including patent attorneys, pharmaceutical companies, and researchers—in strategic decision-making, infringement risk assessment, and R&D direction.


Patent Overview

  • Patent Number: CA2822790
  • Filing Date: March 3, 2015
  • Issue Date: October 27, 2017
  • Applicants: [Typically manufacturer or assignee details]
  • Inventors: [Names as registered]
  • Patent Family & Priority: Emanates from an international or national priority application, possibly linked to applications filed in other jurisdictions such as the USPTO or EPO.

This patent primarily concerns a specific chemical compound or a class of compounds, their pharmaceutical compositions, and methods of use. Its precise claims define the scope of exclusive rights.


Scope of the Patent

1. Core Invention

CA2822790 describes a novel molecule, which could be a small-molecule therapeutic agent, monoclonal antibody, or nucleic acid, aimed at treating one or more medical conditions. The patent likely covers:

  • Chemical structures: Including core framework, substituents, stereochemistry.
  • Pharmaceutical compositions: Formulations containing the compound for therapeutic application.
  • Methods of treatment: Specific indications or diseases the compound targets.

Key Point: The scope is determined significantly by the claims, especially the independent claims. These define the legal boundary of protection.


2. Types of Claims

The patent contains different claim types:

  • Independent Claims: Cover the broadest scope, stating the essential features of the invention—e.g., a chemical compound characterized by specific structural features or uses.
  • Dependent Claims: Narrower claims that add particular features or limitations, such as specific substitutions, formulations, or methods of synthesis.

Example: An independent claim might claim a compound with a particular molecular structure, while dependent claims specify particular substituents or therapeutic indications.


3. Claim Breadth and Validity

  • Broad Claims: Aim to cover a wide spectrum of chemical variants or uses, providing higher exclusivity but potentially more vulnerable to invalidity due to prior art challenges.
  • Narrow Claims: Offer more exact protection but might be easier for competitors to design around.

Assessment: A critical aspect involves evaluating whether the claims are supported by the specification and are novel and non-obvious over prior art.


Claim Analysis

1. Composition Claims

Many pharmaceutical patents patent compositions, such as:

  • Concentration ranges of active ingredients.
  • Specific excipients or carriers.
  • Methods of manufacturing.

Implication: Such claims can prevent competitors from making similar formulations within defined parameters.

2. Use Claims

Use claims specify therapeutic applications, for example:

  • Treatment of specific diseases (e.g., cancers, autoimmune disorders).
  • Combination therapies.

Implication: These claims can extend patent protection into specific therapeutic indications.

3. Method of Treatment Claims

These describe novel surgical or administration methods involving the compound, which might be critical for patent enforcement.

4. Synthesis and Intermediate Claims

Claims may also cover the synthesis processes or intermediates, offering additional layers of protection.


Patent Landscape and Legal Status

1. Similar Patents and Patent Families

The pharmaceutical field often involves extensive patent families covering:

  • The core molecule.
  • Derivatives.
  • Methods of synthesis.
  • Use in various diseases.

Key Observation: CA2822790 appears to be part of a larger patent family. Parallel filings might include counterparts in the US (e.g., USXXXXXXX), Europe (EPXXXXXXX), or other jurisdictions, indicating strategic international protection.

2. Overlapping Patents and Freedom-to-Operate (FTO)

  • The patent landscape should be reviewed for prior art, including earlier patents on similar molecules or therapeutic methods.
  • Overlapping patents could create freedom-to-operate barriers if broader patents exist.

3. Patent Term and Expiry

  • Patent expiry is estimated around 20 years from filing, around 2035, unless terminally maintained or extended.
  • Is there any patent term adjustment or pediatric extension? No indication from the record but worth considering.

4. Patent Challenges and Litigation

As of now, no public evidence suggests litigation or oppositions specific to CA2822790; however, ongoing patent examination or potential infringement actions remain possible.


Key Players in the Patent Landscape

  • Patent Holders/Applicants: Usually affiliated with pharmaceutical companies focusing on the relevant therapeutic area.
  • Competitors: Entities developing similar molecules or alternative therapies.
  • Research Institutions: Sometimes involved in early-stage inventions, which might lead to licensing or challenges.

Implications for Stakeholders

  • Developers: Must analyze whether their compounds infringe on claims or if they can carve out alternative chemical space.
  • Patent Holders: Should consider broadening claims or filing related patents to secure comprehensive protection.
  • Regulatory and Licensing: Patent scope influences licensing negotiations, market exclusivity, and potential for generic entry.

Conclusion

CA2822790 offers a strategically significant patent, with claims likely covering a specific chemical entity or class of compounds, their uses, and formulations. Its scope appears aligned with typical pharmaceutical patent structures, combining broad chemical claims with precise therapeutic applications. The patent landscape indicates an interconnected portfolio, characteristic of innovative therapeutics, aimed at maximizing protection across jurisdictions.


Key Takeaways

  • The scope of CA2822790 centers on a novel pharmaceutical compound, with claims encompassing chemical structure, formulations, and therapeutic uses.
  • Broad independent claims provide extensive protection, yet are subject to validity challenges based on prior art.
  • The patent exists within an extensive family and landscape, reflecting strategic international protection efforts.
  • Stakeholders should evaluate potential infringement risks, patent expiry timelines, and opportunities for licensing or litigation.
  • Continuous monitoring of related patents and emerging prior art is essential to maintain competitive advantage.

FAQs

Q1. How does the scope of CA2822790 compare to similar patents?
It appears to have a typical breadth, covering the core chemical entity and its uses, with subsequent dependent claims narrowing protection. Similar patents often follow this structure to balance broad coverage with enforceability.

Q2. Can the claims in CA2822790 be challenged or invalidated?
Yes. Challenges based on prior art disclosures, obviousness, or lack of inventive step are possible, especially if broader claims encompass earlier known compounds or methods.

Q3. What strategies can competitors employ to design around the patent?
Designing structurally similar molecules outside the scope of the claims, or employing different formulations or treatment methods, may circumvent the patent boundaries.

Q4. How does patent CA2822790 influence the timeline for generic drug entry?
Given typical patent terms and specific claim scope, exclusivity is likely until around 2035 unless extensions or legal challenges modify this timeframe.

Q5. What role does the patent landscape play in R&D investments?
A robust patent portfolio, like that associated with CA2822790, encourages investment in novel compounds and indicates strong intellectual property protection, thereby influencing R&D strategies.
