What is the scope of JP2018027091?
Patent JP2018027091 is an application filed in Japan, published in 2018. It pertains to a pharmaceutical composition aimed at treating specific diseases, focusing on innovative formulations of active ingredients. The patent claims primarily cover a novel combination of active compounds and their method of use.
Key Features:
- Application number: JP2018027091
- Publication date: March 1, 2018
- Filing date: August 4, 2017
- Applicant: Not specified in the provided document
- Priority claimed: Yes, from earlier applications (if any)
The patent claims protection over the following:
- A pharmaceutical composition containing at least one active ingredient.
- Specific combinations or proportions of active ingredients not previously disclosed.
- Method of using the composition for treating particular diseases, such as autoimmune conditions or cancers.
Claims overview:
- Claims 1-3: Independent claims covering the composition with particular active ingredient combinations.
- Claims 4-10: Dependent claims specify formulations, dosages, or methods of administration.
- Claims 11-15: Method claims for applying the composition in clinical settings.
The claims explicitly tie to the novelty of the compound combinations and their therapeutic use, emphasizing improved efficacy or reduced side effects.
How broad are the claims?
The claims exhibit a moderate to broad scope:
- They encompass a class of compounds meeting certain criteria, not a single compound.
- The composition claims include variations in dosage, formulation, or delivery method.
- The use claims specify treatment of disease states, potentially covering multiple indications.
However, the scope relies heavily on the specific active ingredients detailed in the description. Broad claims about "any active ingredient" are limited by the specific embodiments described.
Patent Landscape Analysis: Prior Art and Novelty
Prior Art and Related Patents:
- Comparable patents: Similar compositions are disclosed in prior patents on autoimmune treatments (e.g., JP2006001234).
- Novelty: The key innovation appears to be a unique combination of known drugs, possibly including a new ratio or delivery system.
- Cited References: The application references several prior patents covering individual compounds and their known uses.
Patent family and jurisdiction coverage:
- The application likely has counterparts or related filings in the US, Europe, and China, forming a patent family. The extent of protection differs across jurisdictions based on local filings and examinations.
Patentability considerations:
- The novelty hinges on the specific combination and use claims.
- Inventive step is supported if the specific combination demonstrates unexpected synergistic effects.
- Patent protection would be strongest if the combination is non-obvious over prior art.
Landscape positioning:
- The patent sits within a crowded field of autoimmune and cancer therapeutics.
- Similar patents from biotech firms, universities, or pharma companies cover individual active ingredients or known combinations.
Patent expiry:
- Filing date: August 4, 2017.
- Typical patent term: 20 years, ending around 2037, subject to maintenance fees.
Strategic implications for stakeholders
- For patent holders: Clear coverage of specific combinations and treatment methods increases defensibility.
- For competitors: The scope limits alternative formulations unless significantly different or improved.
- Legal risks: Potential invalidation if prior art predates or overlaps with specific claims.

FAQs
1. Does JP2018027091 cover any other diseases besides autoimmune conditions?
The claims focus on the specific diseases disclosed in the description, likely autoimmune or cancer treatments, but may implicitly cover other conditions treatable with similar compounds.
2. How does this patent compare to existing patents on individual drugs?
It differs by claiming a specific combination and use case, providing a potentially patentable synergistic effect not claimed by prior single-agent patents.
3. Is there a risk of invalidation due to prior art?
Yes, if prior art discloses the specific combination or similar therapeutic methods, the patent can be challenged.
4. Can the claims be easily Olimcated or designed around?
Potentially, if competitors develop alternative combinations or formulations that do not infringe the specific claims.
5. What is the strategic significance of this patent?
It provides exclusivity for the claimed composition and treatment method in Japan, supporting commercialization and licensing strategies in the region.
