- Freedom. Please repost widely.]
-
- A small family company in California is being sued by another company over
- some electronic bingo game machines which allegedly infringe a couple of US
- patents, one of which is #4,455,025 (the claims of the other patent will be
- posted in another message, with a different reply-to address). This patent
- was filed for on September 11, 1981. We are asking the net for any known
- prior art earlier than this filing date (anything done afterward is of no
- use). This patent has some extremely broad claims, so probably any known
- devices which are similar will help, but the closer any prior art is to the
- exact patent claims, the better. The patent claims are at the end of this
- message.
-
- The patent holder is said to have intimidated several other companies out
- of the electronic bingo business. Presently the patent holder is asking
- for an injunction against the alleged infringer, which will cause them to
- lose business (which they need to get revenue for fighting the lawsuit)
- before the trial even begins.
-
- Please mail your prior art directly to lpf-patent-4455025@prep.ai.mit.edu.
- Don't broadcast it on the net! The reason not to tell everyone is that if
- the patent holder finds out about the prior art, they may be able to
- nullify it by asking for reexamination of the patent. So send the prior
- art to the LPF, and the LPF will give it to anyone who is seriously
- interested in fighting the patent.
-
- Please send prior art before the weekend of Saturday, Jan 23, if you can.
- Anything sent after that will still be useful, but sending it sooner will
- give the defendant more time to fight the injunction and to prepare more
- adequately for the trial.
-
- The defendants are also interested in finding expert witnesses familiar
- with these sorts of electronic board games in the 1970s. If you are
- interested in helping, send mail to lpf-patent-4455025@prep.ai.mit.edu.
-
-
- Note that helping to fight this one particular lawsuit isn't going to solve
- the general problem of software patents, though it will help a particular
- defendant. Stopping these sorts of lawsuits once and for all and ridding
- the industry of software patents will require political action. The LPF
- encourages you to become a member. For more information, mail
- lpf@uunet.uu.net.

- Patent claims for USPAT #4,455,025 below.
-
- What is claimed is:
-
- 1. An electronic game board comprising a data input means including a
- keyboard and a remote data entry means, a data processing means including a
- data storage, a data output means including a display, and data transmission
- means;
- said data processing means being responsive to said data input means and
- storing in said data storage bingo card numbers and a bingo pattern
- being played;
- said data output means being controlled by said data processing means and
- signaling the current status of a bingo game;
- said data input means inputting commands and data including called bingo
- numbers;
- said called bingo numbers being independent of said bingo card numbers and
- said bingo pattern;
- said status being determined by said data processing means as a result of
- a mutual comparison of said called bingo numbers with said bingo card
- numbers and with said bingo pattern;
- in combination with at least one tangible bingo card being played with the
- help of said electronic bingo game board; and
- said tangible bingo card bearing identification numbers and bingo numbers
- identical to said bingo card numbers stored in said data storage; and
- communication channel means operatively interconnecting remotely located
- means to said remote data entry means to deliver at least a portion of
- said commands and data from said remotely located means to said
- electronic game board via said remote data entry means.
- 2. The combination of claim 1, wherein said data input means, said data
- processing means, and said data output means cooperatively provide a user of
- said electronic bingo game board with a means for correcting the latest
- erroneously entered data including said called bingo numbers while preserving
- all the previously entered data.
- 3. The combination of claim 1, wherein said display continuously displays
- as many bingo card shaped tabloids as there are bingo cards being played with

- matches between said called bingo numbers and said bingo card numbers.
- 4. The combination of claim 1, wherein said bingo card numbers and said
- bingo pattern stored in said data storage are derived by said data processing
- means as a result of processing of said commands and data entered via said
- data input means excluding said called bingo numbers.
- 5. The combi 5. The combination of claim 1, wherein said commands and data inputted
- via said data input means include at least one of said identification numbers.
- 6. The combination of claim 1, wherein said data input means include a
- means for reading of said tangible bingo cards.
- 7. The combination of claim 1, wherein said tangible bingo cards bear
- two equivalent sets of said identification numbers and said bingo numbers;
- the first set presented in a form convenient for human perception and the
- second set presented in a form convenient for machine reading.
- 8. The combination of claim 1, wherein said electronic bingo game board
- has a means for aligning and retaining said tangible bingo card in a proper
- working position.
- 9. The combination of claim 8, wherein said tangible bingo card overlays
- said display while being in said working position.
- 10. The combination of claim 1, wherein said data processing means include
- a means for generating pseudorandom bingo numbers; each of said pseudorandom
- bingo numbers being generated separately in response to a command entered via
- said data input means, and is being used in lieu of one of said called bingo
- numbers, and is displayed, and transmitted.
- 11. The combination of claim 1, wherein said tangible bingo card is at
- least partially transparent and exhibits said bingo numbers and said
- identification numbers.
