FAQ

What are the typical attorney fees for filing a patent application?

Patent attorney fees vary by technology complexity and attorney experience: PROVISIONAL PATENT APPLICATION: attorney drafting fee: $1,500-$3,500 (simple technology); $3,500-$6,000 (moderate complexity — electronics, software); $5,000-$10,000+ (complex biotech, pharma, materials science); the provisional does not need claims, but a high-quality provisional with full disclosure is critical for later claim scope; USPTO filing fee: $320 (small entity); $160 (micro entity); UTILITY (NON-PROVISIONAL) PATENT APPLICATION: attorney drafting fee: $8,000-$15,000 (most technology); $15,000-$25,000 (complex biotech, pharma, chemical); $5,000-$8,000 (simple mechanical or simple software); design patent drafting: $2,000-$5,000; USPTO filing fees (large entity): $3,060 (utility filing fee + search fee + examination fee); small entity: $1,530; micro entity: $765; note: additional fees for excess claims (>3 independent, >20 total); DESIGN PATENT: USPTO fees (large entity): $760 filing + $600 search + $460 examination = $1,820; PLANT PATENT: USPTO fees (large entity): $860 + $660 + $860 = $2,380; TOTAL COST THROUGH FILING (small entity, moderate complexity technology): provisional: ~$3,000-$5,000 attorney + $320 USPTO; non-provisional (with or without provisional): ~$10,000-$18,000 attorney + $1,530 USPTO; most inventors budget $10,000-$20,000 to get through filing stage.

What does patent prosecution cost after the initial filing?

Prosecution — the examination phase — adds substantial cost after filing: OFFICE ACTION RESPONSE: an office action (rejection) from the examiner requires a substantive response; attorney fees: $2,000-$4,000 per response (simple response); $3,000-$6,000 (complex claim amendments + prior art arguments); $5,000-$10,000 (complex technical response with expert declarations); most applications receive 1-3 office actions before allowance or abandonment; EXAMINER INTERVIEW: phone or in-person meeting with the examiner; attorney fees: $500-$1,500 per interview; highly recommended — significantly increases allowance rates; USPTO ISSUE FEE: when the patent is allowed, an issue fee must be paid; large entity: $1,200; small entity: $600; micro entity: $240; TOTAL COST THROUGH ISSUANCE (small entity, moderate complexity): filing + prosecution + issue fee: $15,000-$30,000+ over 2-4 years; complex or contested applications can cost $50,000-$100,000+; RCE (REQUEST FOR CONTINUED EXAMINATION): if prosecution continues via RCE; attorney fees: $1,000-$3,000; USPTO fee: $900 (small entity, first RCE); CONTINUATION APPLICATIONS: adding continuation applications to develop additional claim scope; similar costs to the original non-provisional; ANNUAL MAINTENANCE FEES: after issuance, maintenance fees are due at 3.5, 7.5, and 11.5 years from grant; large entity: $1,600 + $3,600 + $7,400; small entity: $800 + $1,800 + $3,700; micro entity: $320 + $720 + $1,480; attorney fees for maintenance (optional): $200-$500 per payment to track and pay on time.

What do international patent filings cost?

International protection is significantly more expensive than US-only prosecution: PCT (PATENT COOPERATION TREATY) FILING: attorney fees for PCT application: $2,000-$5,000 (assuming a US non-provisional has already been filed; drafting the PCT requires adapting the US application); USPTO INTERNATIONAL FILING FEES: filing fee: $1,685-$2,670 (depending on number of claims); international search fee: $2,080 (if USPTO is ISA); transmittal fee: $240 (small entity fees approximately 50%); NATIONAL PHASE ENTRY (per country): attorney fees: $2,000-$8,000 per country for national phase entry; official fees vary widely by country; EPO national phase: $5,000-$10,000+ in official fees + translation; translation costs: $0.10-$0.20 per word for patent translations; a 50-page application = $3,000-$5,000 in translation for each non-English country; EUROPEAN PATENT (EPO): attorney fees for EPO prosecution: $5,000-$15,000; EPO examination fees (large entity): €5,000-€10,000+; validation in individual countries: €500-€3,000 per country + translations; Unitary Patent (new 2023): €1,775 + €735 validation fee covers 17+ EU states; JAPAN: attorney fees: $8,000-$15,000; official fees: ¥200,000-¥400,000+; translation: add $4,000-$8,000; CHINA: attorney fees: $4,000-$8,000; official fees: RMB 3,000-8,000; translation: add $3,000-$6,000; TOTAL INTERNATIONAL PORTFOLIO COST (US + PCT + EPO + Japan + China + India): initial filing to prosecution: $100,000-$300,000+; maintenance fees over the patent life: $50,000-$150,000+; large companies spend millions per year on patent portfolio maintenance.

What are the cost differences between large entity, small entity, and micro entity?

USPTO fee discounts can significantly reduce the cost of patent prosecution: LARGE ENTITY: full fees; no discount; any for-profit company that does NOT qualify as small entity or micro entity; SMALL ENTITY (50% DISCOUNT): under 37 C.F.R. § 1.27; qualifies if: an independent inventor with no obligation to assign to a non-small entity; a nonprofit organization (universities, charities); a small business concern (500 or fewer employees under SBA size standards — varies by NAICS code; most tech companies: 500 employees); NOTE: if the patent is assigned to or there is an obligation to assign to a non-qualifying entity, small entity status is lost; MICRO ENTITY (80% DISCOUNT): under § 1.29; qualifies if: small entity PLUS: gross income less than 3× median US household income (~$165,000 in 2024); not named as inventor on more than 4 previously filed patent applications; if employed by or obligated to assign to a university or qualifying institution; the gross income limit is the inventor's personal income, not the company's; LOSS OF STATUS: must stop claiming small or micro entity status as soon as the company no longer qualifies; continuing to claim a discount when no longer eligible = fraud (can result in patent unenforceability); PRACTICAL IMPACT (UTILITY PATENT, PROSECUTION THROUGH ISSUANCE): large entity: ~$5,000-$8,000 in USPTO fees; small entity: ~$2,500-$4,000; micro entity: ~$1,000-$1,600; ATTORNEY FEES: same regardless of entity status; only USPTO fees are discounted; ASSIGNMENT AND OBLIGATION TO ASSIGN: if an independent inventor has an obligation to assign to a large company (employment agreement), the inventor cannot claim small entity status even before assignment.

What does patent litigation cost and how do fees compare to licensing?

Patent litigation is among the most expensive forms of commercial dispute resolution: MEDIAN LITIGATION COSTS (AIPLA SURVEY): cases with <$1M at risk: median $700K total through trial; cases with $1M-$10M at risk: median $2.5M through trial; cases with $10M-$25M at risk: median $3.5M through trial; cases with >$25M at risk: median $5M+ through trial; COST BREAKDOWN BY STAGE: pre-trial filing: $100K-$250K; claim construction (Markman hearing): $200K-$500K; fact discovery: $500K-$1M+; expert discovery: $300K-$600K; summary judgment motions: $200K-$400K; trial preparation: $500K-$1M; trial: $300K-$600K per week; post-trial motions: $100K-$200K; appeal to Federal Circuit: $300K-$600K; DURATION: patent litigation typically takes 2-4 years from filing to trial; ITC (Section 337) investigations: 12-18 months; IPR proceedings: 12-18 months ($15K-$50K); IPR AS COST-EFFECTIVE ALTERNATIVE: filing an IPR to invalidate a patent: $15,000-$50,000 (attorney fees + $19,000-$25,000 USPTO fees); far cheaper than full litigation; PATENT LITIGATION INSURANCE: defendants can purchase patent litigation insurance ($50K-$300K/year premium); covers defense costs; coverage limits vary; ECONOMIC COMPARISON — LICENSING vs. LITIGATION: a patent demand for $5M in total royalties: licensing upfront: $2M-$5M lump sum or royalties; litigation defense cost: $2M-$5M through trial; many defendants settle for licensing fees that are less than or equal to defense costs; hence NPEs set royalty demands just below litigation cost threshold; CONTINGENCY ARRANGEMENT: patent plaintiff attorneys may take cases on 30-40% contingency for strong cases; reduces upfront cost for small patent owners who cannot afford hourly litigation.
