Abstract

A method for detecting potential counterfeiting of print cartridges includes transmitting a message regarding date information stored on a print cartridge installed in a printing device, the message being transmitted to a monitoring server.

Claims

1. A system for detecting potential counterfeiting of print cartridges comprising at least one printing device programmed to:

read date information from an installed print cartridge,

read a current date from a clock in said printing device,

compare said date information and said current date to determine if a difference between said date information and said current date exceeds a threshold,

transmit a message to a monitoring server if a difference between said current date and said date information exceeds said threshold,

wherein said monitoring server is programmed to analyze said message from said printing device for patterns indicative of counterfeiting of print cartridges.

2. The system of claim 1, wherein said monitoring server is programmed to automatically transmit notification of detection of a pattern indicative of counterfeiting of print cartridges.

3. The system of claim 1, wherein:

said printing device includes a memory storing data about said printing device; and

said message conveys said data about said printing device.

4. The system of claim 3, wherein said data about said printing device includes a location of said printing device.

5. The system of claim 1, wherein said printing device has a connection to the Internet over which said message is transmitted to said monitoring server.

6. The system of claim 1, wherein said monitoring server saves messages from monitored printing devices in memory.

7. The system of claim 1, wherein said printing device further comprises an electronic connection configured to be connected to an electronic memory unit on said installed print cartridge in said printing device.

8. The system of claim 1, wherein said printing device is programmed to compare said date information and said current date each time said printing device is powered up.

9. The system of claim 1, wherein said printing device is programmed to compare said date information and said current date when a print cartridge is installed in said printing device.

10. A method for detecting potential counterfeiting of print cartridges, said method comprising:

reading date information from a print cartridge in a printing device;

reading a current date from a clock;

comparing said date information and said current date to determine if a difference between said current date and said date information exceeds a predetermined threshold; and

generating a message indicating a potentially counterfeit print cartridge if the difference exceeds said threshold.

11. The method of claim 10, further comprising transmitting said message regarding said date information stored on said print cartridge installed in said printing device, said message being transmitted to a monitoring server.

12. The method of claim 11, further comprising analyzing said message from said printing device with said monitoring server for patterns indicative of counterfeiting of print cartridges.

13. The method of claim 12, further comprising automatically transmitting notification of detection of a pattern indicative of counterfeiting of print cartridges.

14. The method of claim 11, wherein said message further comprises data about said printing device.

15. The method of claim 14, wherein said data about said printing device comprises a location of said printing device.

16. The method of claim 11, further comprising transmitting said message to said monitoring server from said printing device over the Internet.

17. The method of claim 11, further comprising saving messages from monitored printing devices in memory on said monitoring server.

18. The method of claim 10, further comprising reading said date information from a memory on said print cartridge.

19. The method of claim 10, further comprising comparing said date information and said current date each time said printing device is powered up.

20. The method of claim 10, further comprising comparing said date information and said current date when a print cartridge is installed in said printing device.

21. A system for detecting potential counterfeiting of print cartridges comprising:

means for transmitting a message from a printing device regarding date information stored on a print cartridge installed in a printing device; and

means for receiving said message and analyzing said message and other messages to identify patterns indicative of counterfeiting of print cartridges;

said system further comprising;

means for reading a current date from a clock in said printing device,

means for comparing said date information and said current date, and

means for transmitting said message if a difference between said current date and said date information exceeds a predetermined threshold.

22. The system of claim 21, further comprising means for reading said date information from an electronic memory on said print cartridge.

23. The system of claim 21, further comprising means for automatically transmitting notification of detection of a pattern indicative of counterfeiting of print cartridges.

24. The system of claim 21, wherein said message further comprises data about said printing device.

25. The system of claim 24, wherein said data about said printing device comprises a location of said printing device.

26. The system of claim 21, wherein said means for transmitting said message comprise the Internet.

27. Processor-readable instructions stored on a medium for storing processor-readable instructions, said instructions, when executed, causing a processor to:

read date information from a print cartridge installed in a printing device,

read a current date from a clock,

compare said date information and said current date to determine if a difference between said current date and said date information exceeds a predetermined threshold indicative of expiration of an expected useful life of said print cartridge,

transmit a message to a monitoring server if the difference between said current date and said date information exceeds said predetermined threshold, and

wherein said monitoring server is programmed to analyze said message from said printing device for patterns indicative of counterfeiting of print cartridges.

28. The instructions of claim 27, wherein:

said printing device comprises a memory storing data about said printing device; and

said message comprises said data about said printing device.

29. The instructions of claim 28, wherein said data about said printing device comprises a location of said printing device.

30. The instructions of claim 27, wherein said instructions cause said processor to compare said date information and said current date each time said printing device is powered up.

31. The instructions of claim 27, wherein said instructions cause said processor to compare said date information and said current date whenever a print cartridge is installed in said printing device.

32. The instructions of claim 27, wherein-said instructions, when executed, causing said monitoring server to:

receive said message from said printing device, wherein said message includes said date information from said print cartridge installed in said printing device, and

analyze said message from said printing device for patterns indicative of counterfeiting of print cartridges.

33. The instructions of claim 32, further causing said monitoring server to automatically transmit notification of detection of a pattern indicative of counterfeiting of print cartridges.
