half-siblings   Sometimes ideas are just in the air. And until there's a way of searching for "a site just like the one I'm thinking of," sites will co-evolve, maybe with slightly different spins.

    Gabriel Lewis's ideas, titles illustrated with big stock photographs. Readers can reply and even submit their own ideas. Lewis, a business school student in Richmond, VA, named the site in reference to a 1997 paper by Steven and Burley that tried to determinee how much failure occurs at what development stage of a project. How do you like your odds?
Stage 1: Raw Ideas (3000)
Stage 2: Simple experiments, talks with management, minimal action (300)
Stage 3: Small project (125)
Stage 4: Large project with development efforts (9)
Stage 5: Major development and investment (4)
Stage 6: Commercial launch (1.7)
Commercial Success: (1)

    With counters, timeouts, and money all over the site (including $10 inventors pay to post their ideas and a networking scheme they call "social sales"), Ben Kaufman's '09 startup does a great job mixing marketing, crowdsourcing, and greed.

    The halfbakery cloning experiment that got away.

    Built on top of Gideon Greenspan's open-source "Q&A" engine, SEO and social-marketing consultant Matthew Crowder's site hosts ads aside searchable, categorized ideas. The range of material is broad, from short paragraphs intended to inspire (and catch search query keywords) to reports of innovations observed in the real world and outright inventions. The site allows for votes and comments, with additional features such as sending you email when an idea about a topic matching certain keywords shows up.

    Kids' outreach from the US Patent and Trademark Office, the National Inventors Hall of Fame Foundation, and the Ad Council.

    A by now well-known and stable crowd-funding site (and one of a number of similiar sites.) Select projects to pledge to from an illustrated list with videos by the project owners; select the amount to pledge; get a gift or some form of participation back.

    High-end bounties posted by companies looking for innovations. The site makes a credible attempt at protecting the intellectual property of the large corporations looking for solutions.

    Chris Kuan writes: "If shouldexist is the halfbakery's good twin, then surely Chindogu is the slightly demented older brother who's kept in the back room." Too true.

    "For Sale By Mental Patient" spreads out existentialist, beautifully warped wares like "TIME REMOVING SOAP!!", "BARKLESS TOMATO!!!*" or "NAP SACK!!!!".

    An idea blog with asking prices and legal protection - making it possible to prove that your idea was posted at a certain date, and to track who has viewed it. Discussions of the individual ideas have been outsourced to quicktopic.com.

    Aiming to create a global business-to-business market for technology, this slick startup has scored $20m in funding and charges mostly medium- to large corporations for listing their licensable technology.

    The Asian partner of yet2.com. A challenges-seek-solvers market with enterprise potential (companies can limit solvers to their employees). Also a great example of a terrible logo.

    A free, largely empty, searchable, categorized database, paired with two attempts to sell webspace for $10/year for hosting your own trademark or patent-related site. Go there for the bad grammar, stay for the SQL error messages visibly interleaved with the page layout.

    US Collegiate inventors' competition. Since 1991, fully enrolled college or university students have been competing for prize money, alone or in teams of up to three.

    A moderated idea database that supports submissions, searches, and voting for ideas, with banner ads and many cool text effects.

    Small, short, strongly moderated, beautifully worded and laid out, and ready for re-publication as a book.

    Charles McCarthy's ideas (he seems to have about one attack per week), peppered with mildly topical soft-core porn and relentless self-promotion.

    Hoping to do idea-a-day one better (we'll have to talk about that), Seattle writer Jon Lasser posts his ideas, puns and theories.

    Cléon Daniel's blog and drawings settle at the edge between invention and metaphor.

    A small university spin-off that used to market web software and has no relation to this web site other than by name.

    A food blogger from Alabama, also unrelated to this website other than in spirit. Or stomach.

    The Prior-Art-O-Matic from Kevan Davis.

    Under the subtitle "America's Goofiest Patents", artist and marketing consultant Ted VanCleave comments on illustrations from old and new weird patents.

    Corporate; hosted by salesforce.com. This one has a team of domain experts at starbucks reading and responding. The site has a lot of duplicates, but works well in general.

spinoffs   Halfbakery-related side projects that have sprung up over time.

    Halfbakery quotes and idea summaries, recent-ish, regular-ish, selected at whim.

    An invitation-only multiply social club for current and former halfbakers. Contact po or DrCurry to join.

    A weekly summary written by oscil8.

    Public forum for news and commentary.

    Call Ambulance, Repair Kitchen, the yahoo-hosted halfbakery recipe group.

    Mycroft is a collection of plugins for the Mozilla browser's search bar. Thanks to Roleo Hibachi, one of the thousands of available plugins searches the halfbakery! Search for "halfbakery" on the mycroft site to install it. (On a Mac, fn-click to change search engines.)

    Wagster has follwed through with his idea for a "Halfopoly" layout in spite of [_sctld_] posting a very similar idea earlier. Go coevolution! Designs: Board, 50x50cm board at 180 dpi, Board in A4 segments: 1, 2, 3, 4 from wagster, and generic board game assembly instructions for parts 1-4 from our very own Steve DeGroof.

    The Aphorism Game Show, hosted by freerunner.

    Overbaked, the unmoderated mailing list established by RayfordSteele.

    The first research paper on the halfbakery by nick_n_uit; thanks to absterge for the hosting.

patents   Sites focusing on intellectual property, patents, and patent searches, both serious and silly.

    The Brooklyn Law Incubator & Policy ("BLIP") Clinic is running this site "in anticipation of certain measures of the Leahy-Smith American Invents Act (AIA) taking effect on March 16, 2013." It's free, and lets you publish defensive disclosures by filling out a form.

    US Patent and Trademark Office's searchable patent database.

    US, European, Japanese patent database search that seems faster than the USPTO site.

    European Patent Office, with database search including worldwide patents.

    Browsable and, to a limited degree, searchable documents submitted by companies and gathered from the world at large; full access costs extra.

    Research Disclosure magazine publishes, for a fee, ideas in a way that holds up legally as prior art; patent offices subscribe to this. They're British, they've been doing it for 35 years, they have merely contact information on the web (but not archives) - this is as stuffy as it gets.

    Beautifully laid-out site highlights absurd, useless, or obvious recent patents.

    Same shtick, but the patents are older, and there's more advertising.

    Patrick Andrews' "Invention of the Day" blog, not to be confused with idea-a-day. Given this impressive collection of halfbaked inventions, he doesn't really need an account here, but we're glad to have him anyway.
