Hybrid Model Patents for Start-Ups - Quality Patents, Lower Cost

SUMMARY My name is Sung Oh. I am a Patent Agent (Reg. No. 45,583) with extensive experience prosecuting patents in AI, SaaS, medical devices, electrical systems, and mechanical products. I offer a Hybrid Model Patent Drafting service — clients provide their own initial draft, and I revise the specifications and claims to maximize allowability and minimize examiner rejections. This model leads to quality patents and lower costs. A few Hybrid Model flat fees are as follows: *Patentability Search of Prior Art: $500–$800 *Provisional Applications: $950–$1,500 *Non-Provisional Applications: $2,500–$3,500 *USPTO government fees are paid separately After eight years as a patent attorney, I co-founded several start-ups and learned firsthand how critical capital is to innovation. For early-stage companies, strategically crafted patents—particularly in mechanical systems, software, and AI. I raised over $20 million to fund three technology ventures built on inventions I personally engineered, patented, and brought to market. I also enforced my patents in litigation and achieved a favorable settlement against a major corporation. When those same patents were later challenged, I gained invaluable insight into what makes intellectual property truly resilient—both legally and technically. Today, I apply that experience to help start-ups protect and monetize their innovations—mechanical, software, or AI-based—so they can attract capital while conserving cash, backed by our service guarantee.
