 The Federal Court of Australia found that 2BDB2's macros were based on those included in CA Datacom, and thus infringed on CA's copyright; while there is an interoperability exception under Australian copyright law, the Federal Court adopted a narrow reading of that exception, rendering it largely unavailable to ISVs such as ISI.The Federal Court also found that ISI had illegally relied on CA's confidential information in developing the 2BDB2 product.The first Datacom user conference was held in Dallas in 1974.
