Startup Patent Strategy

The Priority Date is Everything

• The priority date determines what constitutes prior art
• Any public disclosure BEFORE the priority date = prior art against your own patent
• Under AIA, you have a 1-year grace period for your own disclosures — but only in the US
• No grace period in Europe, China, Japan, and most countries

File Before These Triggers

• Product demo at a conference
• Pitch deck shared outside NDA
• Beta users (public use)
• Press release or website launch
• Crowdfunding launch (Kickstarter)
• Academic paper submission
• Any non-NDA conversation with investors or potential customers

Provisional Application Timing

• File a provisional application ($320 large entity / $160 small / $80 micro) to establish a priority date
• Provisional gives 12 months to file the formal non-provisional
• Provisional does NOT need to be perfect — but it must fully describe the invention
• The non-provisional claims the provisional's filing date for any invention described in the provisional

Funding Round Timing

• Series A: investors expect some IP protection or at least pending applications
• A provisional filed before investor conversations is often sufficient
• A pending non-provisional adds more credibility
• Series B/C: investors do more IP due diligence
• Actual issued patents or clear prosecution strategy expected

Rule

• File provisional applications early and often — they are cheap ($320-$1,500 attorney preparation) and buy 12 months while the startup validates the product
• DON'T WAIT for: the product to be 'finished' (file the MVP invention, improve in continuations)
• Funding (the cost of a provisional is small compared to the value created)
• Certainty (file now, optimize later).

Patenting Criteria — File if

• (1) the invention is NOVEL: would a prior art search reveal prior art? if yes, don't waste money on an application likely to be rejected
• Do a quick prior art search before committing to file
• (2) the invention has commercial value: does this invention protect the core product feature? is this how the startup makes money? would a competitor copy this if there were no patent?
• (3) the invention is NOT the secret sauce: trade secrets are often better for core algorithms (the secret sauce that makes the product work)
• Patents require public disclosure after 18 months — the full technical description becomes public
• (4) the invention is relatively easy to reverse-engineer: if a competitor can figure out how you do it from the product, patent it
• If they can't figure it out from the product, trade secret it

Core Product Features

• The specific technical implementation that delivers the value
• Novel algorithms with technical improvement framing (not just 'doing it on a computer')
• Novel hardware configurations
• Novel methods that improve technical performance

Platform/api

• APIs and platform architectures that competitors might copy
• The interfaces others will build on

User Experience Innovations

• Novel UI flows with specific technical implementations
• Accessibility innovations
• Performance optimizations

Don't Patent

• Abstract business processes that lack technical implementation details
• Anything easily searched by competitors with straightforward prior art
• Features that will change dramatically in the next 12-24 months
• Features that are impossible to monitor for infringement (internal server processes)
• TRADE SECRETS vs.

Patents

• Algorithms: if they run server-side and are undetectable from product behavior → trade secret
• If detectable or easily reverse-engineered → patent
• Training data: trade secret (not patentable)
• Model architecture: patent if novel and detectable.

Entity Status Discounts

• SMALL ENTITY (≤500 employees; not university; not partner with large entity): 50% reduction on all USPTO fees
• Example: utility application basic fee $1,960 large → $980 small entity

Micro Entity

• 80% reduction
• Eligible if: (a) qualifies as small entity
• AND (b) has ≤4 previously filed patent applications
• AND (c) gross income ≤3× the preceding calendar year's median household income (~$135,000-$145,000 based on $45,000-$48,000 median HH income × 3)
• AND (d) assigned to an institution of higher education (or not assigned to such an institution)
• Cost: utility application basic fee $1,960 large → $392 micro entity

Provisional Application Strategy

• File provisional applications early ($80-$160 USPTO fees + $500-$1,500 attorney)
• The provisional establishes priority date and buys 12 months
• Use that 12 months to: validate the product
• Raise a funding round
• Decide which inventions merit non-provisional filing
• A well-prepared provisional saves money by: reducing the work needed for the non-provisional
• Allowing focused investment after product-market fit validation

Attorney Cost Reduction

• Work with a patent attorney who understands your technology (reduces back-and-forth)
• Draft a detailed technical memo before attorney meetings (reduces billing time)
• Use less experienced attorneys at large firms supervised by a partner (rates $200-$350 vs. $500-$600+)
• Consider boutique patent law firms specializing in your technology area

Patent Prosecution Roadmap

• Set a budget: early-stage: $15,000-$30,000 per patent application through issuance is reasonable
• Plan to file 3-5 applications in the first 2 years
• Avoid filing patent applications you cannot afford to prosecute through issuance

Defensive Publication Alternative

• If cost is prohibitive, a defensive publication prevents competitors from patenting the same invention (published disclosure = prior art)
• Free to publish
• Doesn't give you a patent, but denies it to competitors

What Vcs Look for in IP Due Diligence

• Pending patent applications (published or unpublished): shows the startup took IP seriously before launch
• Provisional applications: acceptable for seed/pre-seed, less so for Series A+
• Issued patents: highest credibility
• Patent portfolio in strategic technology areas
• Freedom-to-operate: no blocking patents from competitors
• FTO opinion from qualified counsel

Patent Portfolio as Competitive Moat Signal

• Investors want to see that the technology advantage is protectable
• Patent applications signal: 'we have something novel'
• 'we've invested in protecting it'
• 'competitors can't simply copy this without paying us or challenging the patent'
• For B2B SaaS: IP ownership is particularly important — enterprise customers want confirmed IP ownership

Patent Portfolio in M&a

• Acquired startups frequently have their patent portfolios separately valued in M&A
• Patents can represent 20-40% of acquisition value in IP-intensive sectors
• Even a small portfolio (5-10 solid patents) can significantly increase acquisition price

What to Say to Investors

• 'We have [N] provisional patent applications covering our core technology filed [date]'
• 'We have [N] non-provisional applications pending at the USPTO'
• 'Our [technology feature] is covered by [patent number] which issued [date]'
• 'We have a freedom-to-operate opinion from [firm] covering our core product features'
• 'Our patent strategy focuses on [specific technical improvements] that are fundamental to our competitive position'

What to Avoid

• Do not claim patents on obvious or prior-art-covered features
• Investors who do IP due diligence will find this
• Do not over-claim — 'patent pending' does not mean 'patent approved'
• Be prepared to show the actual applications/claims during due diligence

IP Defensive Value

• A startup with a patent portfolio is much harder to bully in litigation
• A threatening letter from a patent troll or competitor is less effective when the startup can respond with its own patents
• FRAND/essential patents: in platform companies, SEP positions can be a revenue source.

Patent Advantages

• 20-year monopoly right (from filing date)
• Public notice to competitors
• Government-enforced right to injunction and damages
• Licensable asset
• Assignable in M&A

Patent Disadvantages

• Full public disclosure of the technology (18 months after filing)
• Expensive to obtain and maintain
• Takes 2-3 years to issue
• Can be challenged and invalidated
• Doesn't protect ideas only their specific implementation

Trade Secret Advantages

• Unlimited duration (as long as kept secret)
• No public disclosure
• No cost to 'obtain' (just keep it secret)
• Protects what patents can't (data, formulas, customer lists, algorithms)
• Immediate protection (no prosecution delay)

Trade Secret Disadvantages

• Independent development by a competitor is a complete defense (no infringement)
• Reverse engineering of the product is a complete defense
• DTSA (Defend Trade Secrets Act 2016): federal civil action
• Actual + exemplary damages + attorney fees
• But enforcement is expensive and difficult
• No monopoly right — cannot block legitimate independent invention

Patent

• When the technology can be detected in the product (reverse-engineerable)
• When competitors might independently invent the same thing
• When the company wants to license the technology
• When the company wants to signal innovation to investors/acquirers

Trade Secret

• When the technology cannot be detected from the product (server-side algorithms; proprietary training data)
• When competitors cannot reverse-engineer it
• When the competitive advantage comes from operational knowledge
• When the technology changes too fast for the 3-year patent prosecution timeline to be useful

Hybrid Strategy

• Patent the detectable aspects (novel UI/hardware implementation)
• Trade secret the server-side core (model weights; training data; proprietary datasets)

Early-stage Startup Default

• File provisional on everything that might be novel (cheap)
• Decide patent vs. trade secret when converting to non-provisional (more information, more resources available).
