USPTO, EPO, and PCT Patent Drawing Specialist | Utility & Design

I specialize in creating USPTO, WIPO, and PCT compliant patent drawings for intellectual property applications, including utility patents, design patents, trademarks, and trade dress. My work focuses on producing clear, precise, and filing-ready illustrations that meet the formal requirements of the USPTO and international patent offices, with close attention to consistency, line quality, and examiner expectations. I regularly work from a wide range of reference material from written descriptions, rough sketches, photographs, to 2D/3D CAD files (STEP preferred) and translate them into professional patent figures such as mechanical drawings, system architectures, flow charts, block diagrams, sectional views, and exploded views. In addition to patent work, I also take on non-patent technical and concept illustrations, where a clean, simplified visual style is needed to communicate complex products or systems. This allows me to balance strict compliance-driven drafting with thoughtful visual judgment when the project permits more flexibility.
