Design Patent Search Services
Design patent searches require specialized expertise that bridges legal knowledge and visual analysis capabilities. Our professional service delivers exhaustive prior art examination to assess patentability, infringement risks, and invalidity potential across all major jurisdictions. We combine systematic database searches with advanced visual comparison techniques to identify even subtle design similarities that could impact your intellectual property rights.
Key Features:
-
Global coverage of USPTO, EUIPO, WIPO and Asian patent offices
-
Locarno Classification system expertise
-
Visual similarity analysis with contour mapping
-
Legal relevance assessment against infringement standards
Advanced Search Methodology
Our proprietary three-phase methodology begins with classification-based searching using the international Locarno system, which categorizes designs into 32 classes and 219 subclasses. This structured approach ensures we examine all relevant design categories where similar prior art might exist. The visual analysis phase employs sophisticated image comparison techniques including standardized viewing angles, proportional analysis, and surface ornamentation evaluation.
Technical Capabilities:
-
AI-powered image recognition for pattern matching
-
3D modeling comparison for complex designs
-
Access to 50M+ design records worldwide
-
Historical coverage dating back 30+ years
Visual Similarity Analysis Process
The core of our service lies in the detailed visual examination process. Each potentially similar design undergoes rigorous evaluation beginning with image standardization to ensure accurate comparisons. Our experts analyze design elements including contours, surface patterns, and three-dimensional features using specialized software tools. The analysis considers both the overall visual impression and specific novel elements that might be claimed in the design patent.
Analysis Components:
-
Image preprocessing and standardization
-
Contour mapping and shape comparison
-
Surface ornamentation evaluation
-
"Ordinary observer" test simulation
Global Search Coverage
We conduct thorough searches across all major design patent jurisdictions including USPTO design patents, EUIPO Registered Community Designs, and WIPO Hague System registrations. Our international coverage extends to key Asian markets where many industrial designs originate, with particular expertise in navigating Japan, Korea and China's unique design patent systems.
Jurisdictions Covered:
-
United States (USPTO)
-
European Union (EUIPO)
-
International (WIPO Hague)
-
