There are four common ways inventors file: form-site services, provisional-only filers, invention-promotion companies, and traditional law firms. Here is how they stack up on the things that actually matter.

LegalZoom is best known for legal forms and business formation. Its patent offerings have centered on provisional applications and attorney-network packages; full utility drafting happens through partner attorneys at close to traditional prices and timelines. There is no multi-country dashboard and no AI drafting of the full specification and claims.
Thoughts to Paper is a filing service focused on provisional patent applications - a fast, inexpensive way to hold a date. But a provisional is never examined and never becomes a patent by itself: you still need the complete utility application drafted and filed within 12 months, which is exactly the part PatentExpress automates.
InventHelp is an invention-promotion company: its core products are marketing and submission services, with patent work referred to independent law firms. Under the American Inventors Protection Act, invention promoters must disclose their client outcomes - ask for those numbers before signing anything. Packages commonly run into the thousands of dollars before any patent application exists.
For complex inventions and contested technology spaces, a seasoned patent attorney drafting from scratch remains the gold standard - and the most expensive path: industry surveys put a typical utility application at $8,000–$15,000+, with weeks of turnaround and hourly billing for office actions. PatentExpress puts an attorney in that same seat for a flat $3,995 working from an AI draft you have already reviewed - the same discipline, a fraction of the cost.
PatentExpress.AI is the only option built by a 26-year patent attorney - former outside patent counsel to Nvidia, VMware, Texas Instruments, Apple, 50+ venture-backed companies, and hundreds of startups - that drafts the complete utility application in minutes, shows it to you before you pay, and files in 150+ countries from one dashboard.
