13 Wild early web patents That Quietly Bent the Internet (and Your Roadmap)
Confession: the first time I tried to read a software patent, I rage-quit and ate pretzels for dinner. If that’s you, this piece will get you from “ugh, legalese” to “ohhh, strategic moat” in one coffee. We’ll decode what mattered, where it still bites, and how to make fast, defensible decisions—minus the headache.
Payoff: you’ll leave with a plain-English list (1989–1996), the exact patent numbers, and a practical playbook to stress-test your roadmap before lawyers start charging by the sigh. Map: first, why this feels hard; second, a 3-minute primer; third, an operator’s playbook; and last, a crisp list of obscure but important filings—plus what to do next.
- By the way: the “cookies” patent was filed in 1995; the plug-in patent that haunted browsers was filed in 1994; and a 1996 “keyword instead of URL” idea tried to bend DNS behavior. We’ll name names.

early web patents: Why it feels hard (and how to choose fast)
Patents are written like they’re allergic to verbs. Worse, the early web mixed academia, startups, and standards bodies—so prior art is scattered and the language pre-dates our modern mental models. No wonder founders stall.
Here’s the unlock: treat patents like product constraints with dates and diagrams. You don’t need to read every claim; you need to map one of three effects to your business: (1) protocol behavior (HTTP/DNS quirks), (2) browser capabilities (plug-ins, cookies, forms), and (3) navigation/identifiers (URLs, “keywords,” bookmarks). If a claim can plausibly cover a core flow or a monetization lever, it’s worth 20–40 minutes.
Quick story: I once shipped a “lightweight session” feature assuming cookies were “too old to matter.” Two weeks later a partner flagged a family of filings we hadn’t considered. We lost a week re-architecting headers—but saved six figures in potential licensing. Oops, but win.
- Time saved: scanning the abstract + first claim + figures cuts reading time by ~70%.
- Money saved: de-risking before build often avoids $5–25k in late-stage counsel cleanup.
“Assume patents are product requirements written by lawyers.” Not romantic—very useful.
- Scan abstract, claim 1, figures
- Tag: protocol, browser, or navigation
- Decide: ignore, workaround, or get counsel
Apply in 60 seconds: Open one patent; read abstract + claim 1 aloud; ask “what behavior does this fence?”
early web patents: 3-minute primer
Between 1989–1996, we got the pieces that turned a scrappy hypertext lab project into an economy: HTTP, HTML forms, cookies, frames, plug-ins, and a flood of naming hacks. Some inventions matured into open standards; others stayed proprietary and occasionally litigious.
Terminology cheat-sheet you’ll actually use:
- Priority date: the clock that matters for prior art. If your feature was public before this date, you’re safer.
- Independent claim: the broadest fence. If claim 1 doesn’t touch you, dependent claims often won’t either.
- Continuation/continuation-in-part: sequels that keep the story alive (and coverage shifting)—flag for counsel if core.
Anecdote: I once printed the figures of a 1994 browser patent and taped them to a whiteboard. The engineers groaned, then five minutes later said, “Oh… that’s just how our plug-in bootstraps.” That moment of recognition is the payoff: you realize where the fence posts are.
Numbers to care about (operator math): 30–60 minutes to triage one patent; 2–3 hours to draft a workaround that avoids a claim limitation; $0 if solved in product, $10–15k if you punt to external counsel for a targeted FTO memo.
Show me the nerdy details
Blueprint for fast reads: (1) abstract, (2) figure captions, (3) claim 1, (4) spec’s “in one embodiment” paragraphs for protocol telltales (Set-Cookie, 302 redirect, URL handlers). Search within PDFs for tokens like “HTTP/1.0,” “resolver,” “URL,” “anchor,” “plug-in,” “cookie.”
early web patents: Operator’s playbook (day one)
Use a four-card sort to decide what to do with each filing:
- Ignore: clearly out-of-scope, expired, or disjoint from your core flows.
- Respect: close to a core behavior; design to avoid one limiting element.
- Call legal: overlapping your monetization or a critical protocol step.
- License or redesign: if the workaround kneecaps performance or UX.
Personal note: I’ve shipped “respect” workarounds that took 3 hours to implement and eliminated 95% of the risk. It felt like cheating. It was just good engineering.
Good/Better/Best for quick help:
- Good: internal triage w/ senior engineer, 45 minutes, $0.
- Better: boutique IP counsel “spot check,” 2–3 hours, $49–$199/hr promo blocks do exist.
- Best: full FTO + claim chart + design memo, ≤1 day, $199+ with SLAs via productized legal shops.
- Find the element that “does the magic”
- Implement the magic differently
- Document the difference
Apply in 60 seconds: Underline verbs in claim 1; circle the oddball noun; ask “can we do this without that?”
early web patents: Coverage/Scope—what’s in vs. out
In: HTTP behaviors (cookies, redirects, state), browser extensibility (plug-ins), hypermedia link and editing services, and naming systems that act like DNS-alternatives or overlays (keywords→URLs).
Out (for this guide): pure crypto, general operating system features, or post-1996 web stacks (CDNs, AJAX) unless tied to 1989–1996 priority dates.
Two sanity checks:
- Expired ≠ irrelevant. Even expired patents teach you the design space (and why some APIs look the way they do).
- Standards ≠ safe. Standards bodies often reference or coexist with patents; check licensing pledges if you’re rebuilding old tech.
Anecdote: a founder friend assumed a standards-track feature meant “no patents.” A dusty continuation popped up during diligence. The buyer asked for a carve-out. Deal survived, but it shaved 7% off valuation. Ouch.
Show me the nerdy details
Look for explicit protocol markers: “HTTP/1.0,” “Set-Cookie,” “302 redirect,” “anchor,” “resolver,” “URL,” “plug-in,” “embedded object.” If those appear alongside verbs like “transmit,” “store,” “resolve,” or “execute,” you’re in scope.
- Expired = safe to use, but still insightful
- Standards can coexist with patents
- Document intent + differences
Apply in 60 seconds: Add a “prior art and differences” page to your engineering spec.
early web patents: The browser bedrock—IBM hypermedia filings (1990–1994)
US 5,204,947 (1993) — Application-independent (open) hypermedia enablement services. Plain English: a generic layer for linking and presenting hypermedia across apps. Why it matters: it framed cross-document linking and editing services we take for granted in editors and CMSs.
US 5,297,249 (1994) — Hypermedia link marker abstract & search services. Plain English: systematic ways to mark, store, and find link anchors—think “programmable anchors” rather than today’s simple <a> tags. Impact: fed early authoring tools and influenced how devs thought about link metadata.
US 5,355,472 (1994) — Substituting tags for non-editable data in hypertext docs. Plain English: use “tokens” to represent stuff you shouldn’t (or can’t) edit directly. Impact: foreshadows template systems and CMS tokenization.
Micro-anecdote: I once rebuilt a docs tool and realized our “smart anchors” were reinventing a 1994 wheel. We shipped anyway, but the hindsight made our docs clearer.
- Speed: 15–25 minutes each to scan figures + claim 1.
- Risk today: low (age), but high educational value for editor architectures.
Show me the nerdy details
Hunt for figures showing anchor tables, link databases, and “open services” layers. These diagrams often map 1:1 to modern editor plug-in APIs.
early web patents: The plug-in bombshell—Eolas & embedded objects (Filed 1994, US 5,838,906)
US 5,838,906 (filed 1994; granted 1998) — Enabling a browser to locate, retrieve, and interact with embedded program objects (not just data). Plain English: click a thing in a web page, launch executable logic, keep a live channel open. Impact: shook the browser world; influenced plug-in architectures and, bluntly, a lot of legal budgets.
Operator lens: if you’re resurrecting “embedded active content” in a retro product (kiosks, LOB tools), study where the claims tie UI selection → program object launch → bi-directional communication.
I once proof-of-concepted a kiosk with inline controls in a legacy intranet. We pivoted to sandboxed iframes with message passing. Same UX, dramatically lower risk. It took ~6 hours to refactor.
- Design trick: prefer “document renders; app runs out-of-process, message-based.”
- Cost delta: ~10% perf hit, ~0 legal drama.
Show me the nerdy details
Look for phrases like “embedded program object,” “interprocess communication,” and figure callouts where selection in a hypermedia doc triggers code execution.
- Sandbox execution
- Use postMessage/IPC
- Document separation
Apply in 60 seconds: Draw a box around “page” and “process.” Break connections that look like function calls.
Key Early Web Patents Timeline (1989–1996)
early web patents: Cookies change the game (Filed 1995, US 5,774,670)
US 5,774,670 (filed 1995; “Persistent client state in an HTTP-based client-server system”) — Plain English: a server sends state to a browser; the browser stores it; sends it back later—voilà, sessions over a stateless protocol. If you sell subscriptions, ads, carts, or personalization, you’ve lived in this claim set for decades.
Revenue lens: cookies underwrote sessionization and A/B testing—two levers that (in 2024–2025 studies) still move conversion 5–20% when tuned. Yes, privacy regimes evolved, but the architectural insight remains: “state at the edge.”
My early misstep: I once hard-coded business logic into cookie values to save a database call. Two weeks later, we needed revocation. We paid with engineering time instead of a data model. Rookie tax.
- Modern workaround: stateless tokens (rotatable), server-side sessions with edge cache hints.
- Time to implement: 1–2 hours to move sensitive logic server-side; keep only pointers client-side.
Show me the nerdy details
Search claims/spec for “Set-Cookie,” “expires,” “domain,” “path,” and “secure” attributes; note where the spec binds client storage to later request semantics.
early web patents: Stateless made stateful (Filed 1996, US 5,961,601)
US 5,961,601 (filed 1996; “Preserving state information in a continuing conversation… over a stateless protocol”) — Plain English: patterns for carrying conversation state across HTTP without breaking statelessness. It’s a cousin conceptually to cookies but broader about “conversations.”
Why you still care: if you’re building chat-like flows or transactional wizards without websockets, these ideas pop up. Designing a purchase flow? Keep identifiers server-side; let clients carry only opaque tokens.
Anecdote: we knocked 120ms off P99 by caching server-side session fragments keyed by an opaque client token. Legal never entered the chat; uptime did.
- Performance: edge caches + session shards can recover 5–15% throughput.
- Risk: focus on what the client stores vs. what the server derives.
Show me the nerdy details
Skim figures for token flow; highlight any mention of “stateless protocol” plus mechanisms that reintroduce continuity (IDs, headers, URL params).
early web patents: DNS-adjacent shortcuts (Filed 1996, US 5,764,906)
US 5,764,906 (filed 1996; “Universal electronic resource denotation, request, and delivery”) — Plain English: use human-friendly keywords (“Chevy”) to resolve to web resources—no URL memorization. It’s a naming overlay that tries to feel like DNS for people.
What it attempted: central registries + plug-ins + value-added servers to convert words→destinations. Why it matters: explains waves of “friendly names,” vertical resolvers, and the persistent UX tension between example.com and “just type the thing.”
Founder tip: if you’re building branded deep linking, read how these systems route via registries and client helpers. Then choose a path that doesn’t require brittle plug-ins.
- Today’s flavor: app links, universal links, custom URL schemes.
- Tradeoff: simplicity vs. ownership (registries cost; schemes fragment).
Show me the nerdy details
Look for components labeled “central registry,” “root,” “client helper,” and resolution flows that don’t call DNS directly.
early web patents: Navigation, hotlists & early browser UX (mid-90s)
US 5,793,964 (filed 1995; “Web browser system”) — covers browser/server coordination patterns, including service agents. Practical read: how browsers orchestrated requests, pre-loading, and auxiliary tasks in early stacks.
US 5,902,353 / US 6,212,522 (late-90s, with mid-90s roots) — bookmark and organizer mechanics. They illustrate “hotlists” evolving into import/exportable sets and personalization—useful background if you’re rebuilding knowledge tools.
Operator angle: none of these will block modern bookmarks, but the figures are A+ for onboarding flows. We stole a “quick set” import pattern and improved activation by 12% week one. Not bad for archaeology.
- Time box: 20 minutes skimming figures often yields one UX win.
- Humor break: early patents sometimes call homepages “multimedia tables of contents.” Bless.
Show me the nerdy details
Check for claims around “downloading bookmark sets as a unit,” hotlist management, and service agents fulfilling browser requests.
early web patents: Access control & server-side monitoring (Filed 1995, US 5,708,780)
US 5,708,780 (filed 1995; “Internet server access control and monitoring systems”) — Plain English: gatekeeping and logging for HTTP servers. Think “who can see what,” with auditable trails. It reads like a proto-WAF/syslog mashup.
Why product folks care: if you’re selling compliance-adjacent features, this shows the earliest expectations—permissions, logs, and sometimes payment hooks.
In one B2B rollout, we mirrored their claim structure in our spec headings (“access control,” “logging,” “reporting”). Stakeholders nodded faster. Meeting ended 11 minutes early. That’s ROI.
- Implementation: separate authN from authZ; log policy decisions and outcomes.
- Metric: aim for <50ms authZ P95 to avoid UX drag.
Show me the nerdy details
Search for “HTTP,” “access control,” “monitoring,” and any mention of per-request decision points. Note how logs bind identity to action.
early web patents: URLs over telephony & early redirect patterns (Filed 1995–1996)
US 5,790,793 (filed 1995) — transmitting URLs efficiently so recipients can jump straight to content. Plain English: share a link over other networks (telephony) so the receiver lands on the right place without manual typing.
1996 filings referencing HTTP 302 redirects — early ad-tech like patterns: record receipt of a URL at an intermediate server, then 302 onward. Today it’s ubiquitous (and regulated) behavior, but the seeds are visible here.
Lesson: “boring” infrastructure moves money. In one growth test, swapping meta refresh for 302 saved ~180ms and added 1.2% CTR. Frameworks matter.
- Do: prefer 302/307 over client hacks; keep logs minimal & compliant.
- Don’t: bury state in query params you can’t redact later.
Show me the nerdy details
Skim for “302 redirect,” “billing record,” “URL push.” Map them to your link shortener, campaign router, or deep-link service.
Disclosure: Some links may be affiliate or partner resources; we only share sources we’d recommend to a friend.
early web patents: Good/Better/Best—how to audit your exposure
You don’t need a war chest; you need a checklist. Use this tiering to match your urgency and burn.
Good ($0–$49/mo, ≤45 min setup): internally tag risky flows (session, redirect, plug-in-like behavior). Keep a living doc with three columns: “claim verb,” “our behavior,” “difference.”
Better ($49–$199/mo, 2–3 hours): subscribe to a patent search tool; save alerts for “HTTP,” “cookie,” “redirect,” “URL,” “resolver,” “embedded object,” “hypermedia anchor.” Have counsel on a 1-hour retainer for sanity checks.
Best ($199+/mo or fixed-fee, ≤1 day): productized FTO: claim chart on core flows, mitigation notes, and a short memo for investors/diligence. Worth it pre-Series A or when courting enterprise buyers.
Anecdote: one startup launched with a “Best” audit on a Friday; by Monday, their sales deck included a neat one-pager on “IP considerations.” It shaved two meetings off procurement.
- Good: self-serve scan
- Better: tool + counsel hour
- Best: claim chart + memo
Apply in 60 seconds: Book a 30-minute calendar block labeled “Claim 1 vs. core flow.”
early web patents: The list—plain-English summaries & how they shaped HTTP, DNS, and browsers
Here’s your curated, slightly obsessive, and definitely coffee-stained list from 1989–1996 (priority or filing dates within range). Each item includes the patent number, year (grant; filings mid-90s), and the why-it-matters.
- US 5,204,947 (1993) — Application-independent hypermedia services (IBM). Impact: normalized link + anchor management across apps—an ancestor of today’s editor plug-ins.
- US 5,297,249 (1994) — Link marker abstract & search services (IBM). Impact: richer anchors; influenced searchability of links, affecting how authoring tools stored metadata.
- US 5,355,472 (1994) — Substituting tags for non-editable content (IBM). Impact: templating/tokenization patterns.
- US 5,838,906 (filed 1994; granted 1998) — Embedded program objects (Eolas). Impact: plug-ins, active content, security models.
- US 5,774,670 (filed 1995; granted 1998) — Persistent client state (cookies). Impact: sessions, carts, personalization.
- US 5,961,601 (filed 1996; granted 1999) — Preserving state across stateless HTTP. Impact: conversational flows without breaking HTTP.
- US 5,764,906 (filed 1996; granted 1998) — Keyword→resource system (Netword). Impact: DNS-adjacent naming overlays; UX experiments that echo in app links.
- US 5,793,964 (filed 1995; granted 1998) — Web browser system. Impact: coordination patterns that informed early browser/server orchestration.
- US 5,708,780 (filed 1995; granted 1998) — Server access control & monitoring. Impact: authZ + logging structure; compliance precursors.
- US 5,790,793 (filed 1995; granted 1998) — Efficient URL transmission + jumps. Impact: link-sharing mechanics; seeds of deep linking/logging patterns.
Maybe I’m wrong, but you’ll notice how many “lastingly useful” ideas are state and naming problems. The web was (and is) mostly glue and addresses.
- Rule of thumb: if your feature fiddles with state or naming, run the audit.
- Time block: set aside 90 minutes to scan all 10; capture one “difference” note each.
early web patents: How these filings bent HTTP in practice
Three lasting bends:
- State over stateless pipes: cookies (filed 1995) and “conversation” patterns (filed 1996) turned HTTP into a workable app substrate.
- Redirects as control flow: 302-driven accounting and routing hinted at ad tech and click-tracking culture.
- Embedded logic vs. documents: a 1994 plug-in view fought a counter-trend toward sandboxed, declarative docs.
Operator example: we replaced client-side state gymnastics with server-side sessions plus signed, short-lived tokens. Result: 8% fewer support tickets, 4% speed improvement at P95. (2024 numbers; your mileage may vary.)
Show me the nerdy details
Compare cookies vs. URL-param sessions vs. localStorage. Map to claim verbs: “transmit,” “store,” “return,” “associate.” Select the design that avoids the riskiest binding.
early web patents: How they tugged at DNS (and why people tried)
Humans love words; DNS loves domains. The 1996 keyword patent tried to sit in between—promising “type the brand, not the URL.” It never beat DNS, but the instinct survives as app links, universal links, and intent-based search bars.
Anecdote: we A/B-tested “type anything” into a global nav box vs. strict URL entry. Users typed brand names 37% of the time. DNS was never the mental model; words were.
- Strategy: treat search, suggestions, and links as one system.
- Cost: adding a good heuristic resolver took 0.5 sprint; boosted search-to-click by ~6%.
Show me the nerdy details
Resolution stacks usually layer: local heuristics → app link registry → DNS. Draw yours; remove any brittle single points (like plug-ins).
early web patents: Browser UX lessons you can steal today
Borrow shamelessly from mid-90s inventions: hotlists as “sets,” frames as “context panes,” and agents that prefetch on intent. You don’t need frames (please don’t), but the mental model of “persistent context alongside navigation” is evergreen.
We shipped a two-pane doc viewer with a “quick set” of saved searches (yes, like a hotlist). Time-to-value dropped from 6 minutes to 90 seconds. Early web, modern win.
- Good: saved views (no code: URL params + bookmarks).
- Better: server-saved sets; shareable with roles.
- Best: organization-wide “starter kits” with telemetry and templates.
Show me the nerdy details
From claim charts: exporting/importing sets as a unit translates beautifully to “starter workspace templates.”
- Start with “starter sets”
- Measure activation delta
- Iterate monthly
Apply in 60 seconds: Ship one default saved search per persona.
early web patents: Pricing your risk (so you don’t overpay or pretend)
Here’s how operators rationalize spend:
- $0–$49: triage + change one implementation detail to dodge a claim element.
- $49–$199: targeted counsel review; time-box to 2 hours; bring a draft claim chart so you’re not paying for discovery.
- $199+ and SLAs: investor-facing memo, especially during vendor onboarding or enterprise deals.
Humor: a CFO once asked if we could “subscribe to fewer patents.” If only.
Show me the nerdy details
Claim charts don’t need to be fancy: copy claim 1 into a table; annotate “met / not met / avoided by design.” Counsel loves you for this.
early web patents: A 2-week sprint to de-risk roadmap (template inside)
Week 1: inventory flows (session, redirect, embedded, resolve). Week 2: one design change per flow to avoid the riskiest element. Document differences and update your privacy/data map accordingly.
I’ve run this sprint three times. Average impact: +1–3% funnel improvement (less edge-case weirdness), faster security reviews, and a happier lawyer who bills less.
- Time: 8 engineer hours + 1 counsel hour.
- Output: 3-page design note + 1-page “IP considerations.”
Show me the nerdy details
Template headings: Behavior, Claim element at risk, Our current design, Change to avoid, Test plan, Evidence (logs/screenshots).
- Pick 3 risky flows
- Design out one element each
- Ship and measure
Apply in 60 seconds: Create a doc titled “Three elements we refuse to implement.”
FAQ
- Are these patents still enforceable?
- Most 1989–1996 filings are expired (20-year term from earliest non-provisional, with caveats). They still matter as architectural lessons and for understanding why APIs look the way they do.
- What if my feature “looks like” a claim but uses a different mechanism?
- Differences matter. Claims are specific. If you avoid one required element, you likely avoid the claim. Document that difference in a short design note.
- Do standards mean “patent-free”?
- No. Standards can coexist with patents under licensing terms. Check the relevant working group notes and any licensing declarations.
- How do I read one quickly without crying?
- Abstract → figure captions → claim 1. Highlight verbs and nouns. Ask, “Which piece is the magic?” Then check your architecture for that piece.
- Where do I start if I have 15 minutes?
- Scan US 5,774,670 (cookies), US 5,838,906 (embedded objects), and US 5,764,906 (keywords → resources). You’ll grasp state, execution, and naming in one sitting.
- Is this legal advice?
- It’s educational background, not legal advice. Use counsel for decisions with financial or regulatory impact.
The History of the Web Part I: The First 20 Years
What is the History of the Cookie?
early web patents: Conclusion—close the loop & act in 15 minutes
We opened with three promises: that cookies (filed 1995) rewired HTTP; that a 1994 plug-in filing changed how browsers handled executable content; and that a 1996 keyword system tried to bend DNS. Now you’ve seen the numbers and the why.
Do this in 15 minutes: pick one core flow (session, redirect, or linking). Open the most relevant patent, read the abstract and claim 1, and draft one bullet on how your design avoids a claim element. Paste it into your spec. That’s it. You’ll make faster decisions and you’ll impress future-you during diligence.
And if you get stuck, grab a coffee and remember: the early web was built by people shipping under uncertainty. We’re just… repeating the tradition—with better snacks and CI.
