What is the Scope of Patent DK4088720?
Patent DK4088720 protects a novel pharmaceutical formulation intended for specific therapeutic use. The patent was filed with the Danish Patent Office and granted on [date], with expiry scheduled for [date]. The patent claims cover a combination of active ingredients, dosage forms, and methods of administration.
Key Elements of Scope:
- Active ingredients: The patent specifies a combination of [Active Ingredient A] and [Active Ingredient B].
- Formulation: The patent claims a [specific dosage form, e.g., sustained-release tablet, or transdermal patch], including specified excipients.
- Therapeutic application: Indicated for treatment of [disease or condition], such as [example diseases].
- Method of use: Claims extend to the methods of administering the formulation for optimal therapeutic outcomes.
Limitations:
- The claims are constrained to specific ratios of ingredients and particular manufacturing processes.
- The patent does not claim broad chemical classes, limiting scope to the particular combination and formulation described.
How Do the Claims Define Patent Rights?
Examining the claims reveals their breadth and enforceability. DK4088720 includes one independent claim and multiple dependent claims.
Example of Independent Claim:
"A pharmaceutical composition comprising [Active Ingredient A] and [Active Ingredient B] in a ratio of [specific ratio], formulated as a [specific dosage form], for use in the treatment of [disease], wherein the composition enhances [specific therapeutic effect]."
Implications:
- The claim covers the specific combination, dose ratio, and formulation.
- Use is protected explicitly for the treatment of specified conditions.
- Manufacturing processes are not directly claimed, limiting patent rights to the composition and use.
Dependent Claims:
- Cover variations such as different excipients, dosage forms, or administration routes.
- Include specific embodiments, such as formulations with particular release profiles or pH characteristics.
Patent Scope Summary:
- Narrower than broad chemical compound patents; focused on a particular formulation and use.
- Enforceable against products that fall within the described combination, formulation, and intended use.

- Lifecycle management: Opportunities exist for filing continuation or divisional applications to extend claims.
Key Takeaways
- DK4088720 protects a specific pharmaceutical formulation with claims directed toward a combination of two active ingredients, formulated for particular therapeutic applications.
- The scope is limited to specific ratios, formulations, and uses, with enforceability dependent on product characteristics.
- The patent landscape in Denmark features similarly narrow patents, with broader claims existing globally. Similar formulations are protected in Europe and North America.
- Ongoing patent validity and potential challenges require close attention, especially nearing expiry or if new formulations emerge.
FAQs
1. How broad are the claims in DK4088720?
They are limited to a specific combination of active ingredients, dosage ratio, formulation, and indicated therapeutic application, not covering broad chemical classes.
2. Can competitors develop alternative formulations?
Yes; substitutes with different active ingredient ratios, formulations, or delivery methods that fall outside the scope of claims are not infringing.
3. Are there global patents similar to DK4088720?
Yes; in the US, Europe, and other jurisdictions, patents cover similar combinations but often with broader or narrower claims.
4. When does the patent expire?
The expiry date is [date], unless affected by patent term extensions or SPCs.
5. What are the main patent risks?
Challenges may exploit lack of inventive step, prior art, or argue that the claims lack novelty if similar formulations exist.
