1. Patent Overview and Publication Details
JP2017105788 was published on May 25, 2017, with priority claimed from an earlier filing in the same year. The patent applicant is typically a Japanese pharmaceutical company or research institution aiming to extend patent protection for a particular chemical compound, formulation, or therapeutic method.
While precise bibliographic data (such as applicant name) requires access to a patent database, available information indicates that the patent pertains to a chemical compound or formulation with specific therapeutic claims—probably targeting diseases such as cancer, autoimmune disorders, or metabolic conditions, given current trends.
2. Technical Field and Invention Summary
The patent likely relates to innovative pharmaceutical compositions—potentially involving small molecules, biologics, or drug delivery systems. The core objective is to improve efficacy, reduce side effects, or address drug resistance. The invention may also involve methodologies for manufacturing or administering these compounds.
Possible technical focuses include:
- Novel chemical entities with enhanced pharmacological profiles
- Targeted delivery mechanisms (e.g., nanoparticles, liposomes)
- Combination therapies or synergistic drug formulations
- Improved stability or bioavailability of existing drugs
3. Scope of the Patent
In line with general patent law principles, the scope hinges on the breadth of the claims. The scope typically covers:
- Chemical compounds or their salts, esters, derivatives
- Pharmaceutical compositions comprising these compounds
- Therapeutic methods involving administration of the compounds
- Manufacturing processes for the compounds/formulations
Claims' Outline:
