Mitel, Inc. v. Iqtel, Inc. is a United States copyright case, decided by the Tenth Circuit Court of Appeals in 1997, about whether the numeric “command codes” used to program a telecommunications call controller are protected by copyright. Mitel sued a competitor that had built its controller to accept Mitel’s codes. The court held that Mitel was unlikely to succeed because the codes were either unoriginal or dictated by external functionality and compatibility requirements.[1] For software asset managers it illustrates the limits of copyright as a way to control compatible products.
Background
Mitel and Iqtel made competing call controllers. These are devices installed at business premises, usually by long distance carriers, to automate carrier selection and activate features such as speed dialing.[1] Mitel began selling its Smart-1 controller in 1985. It devised “an instruction set of over sixty four-digit numeric command codes” and “published and copyrighted manuals” describing how technicians program the controller with them.[1] Each code has a three-digit “register” identifying the function and a final “description” digit that selects a setting, or “value”. For example, 0066 sets the RS-232 baud rate to 4800.[1]
Iqtel began selling its IQ200+ controller in 1994. Because Mitel held a large share of the market, Iqtel concluded that technicians would not learn a second instruction set. According to the court, Iqtel copied Mitel’s codes “in three important respects”.[1]
- A “Mitel Translation Mode” that accepted Mitel command codes and translated them.
- An appendix to Iqtel’s manual cross-referencing Mitel and Iqtel codes.
- Use of Mitel’s values and descriptions in Iqtel’s own codes for common functions.
The dispute
Mitel filed a copyright infringement action on 1995-04-25 and sought a preliminary injunction.[1] Iqtel did not dispute copying. On appeal it admitted “that it copied virtually the entire set of Mitel command codes”.[1] Nor did Iqtel appeal the finding that Mitel owned a valid copyright. The case therefore turned on whether the copied elements were protectable expression.[1]
On 1995-08-23 the District Court for the District of Colorado denied the injunction on several grounds. It held that the codes were a method of operation under 17 U.S.C. § 102(b), that they were unoriginal, and that they were unprotectable as scenes a faire. It held in the alternative that Iqtel’s copying was fair use.[1][3]
Decision or outcome
The Tenth Circuit (Tacha, J., for a panel with Godbold and Holloway, JJ.) affirmed on 1997-09-22.[1][2]
- Method. The court applied its abstraction-filtration-comparison test to separate idea from expression. It expressly declined “to adopt the Lotus court’s approach to section 102(b)”, referring to the First Circuit’s decision in Lotus Development Corp. v. Borland International on the command menus of the Lotus 1-2-3 spreadsheet.[1]
- Registers and descriptions. These were unoriginal: “Mitel’s arbitrary selection of a combination of three or four numbers required de minimis creative effort”, and Mitel’s own witnesses testified that the choices were arbitrary.[1]
- Values. The values were original expression but unprotectable as scenes a faire, because “they were dictated by external functionality and compatibility requirements of the computer and telecommunications industries”. Examples were customer demand, compatibility with older Mitel controllers and the 40-millisecond minimum touch-tone length of the telephone network.[1]
- Fair use. Having found the codes unprotected, the court did not decide whether Iqtel’s copying was fair use.[1]
The court concluded that Mitel had “failed to demonstrate that its command codes contain expression that is original and goes beyond the necessary incidents of the ideas which the codes express”, and affirmed.[1] The decision concerned only the preliminary injunction. The retrieved court records do not show any later proceedings.
Significance for software licensing and SAM practice
The case concerns copyright, not a licence agreement, but it bears on licensing in two ways.
First, a vendor’s ability to stop compatible products or services depends on what the law protects. Copyright protected Mitel’s manuals as written works. It did not protect the arbitrary or functionally dictated codes that a compatible device had to accept.[1] Contractual controls work differently. Mitel’s current EULA, for example, limits use to purchased Entitlements and forbids reverse engineering and derivative works.[4] Such terms bind licensees, but not competitors outside the contract. See Mitel Software Assurance, Licenses & Services and EULA.
Second, for organisations running mixed telephony estates, the ruling describes the economic logic of compatibility. Iqtel built a translation mode because technicians and their employers would not bear the cost of learning a second command set.[1]
Lessons learned
- Copyright in documentation is not control of the interface. Mitel owned a valid copyright in its manuals, yet could not stop a competitor from accepting the same codes.[1] When assessing vendor claims about third-party compatible tools, check what the vendor actually claims to own.
- Arbitrary or functionally dictated elements may be unprotectable. The court treated arbitrary numbering as unoriginal, and settings driven by hardware, compatibility and industry practice as scenes a faire, even though Iqtel copied “virtually the entire set”.[1]
- Contract terms are the more reliable control. The dispute shows the limits of copyright. For licensees, the binding restrictions are those in the licence agreement and order documents, which this case did not address.
