The US federal judge who has been facilitating the ongoing US-based battle between Samsung and Apple over various patents, Judge Lucy Koh, has again taken a familiar path by ordering the two parties to narrow down the claims against each other. In a repeat of the run-up to the first patent trial, which Apple won handily but which is currently under appeal, Koh limited to the parties to no more than 25 patent claims and 25 products. Her rationale for the limitations was that both parties should know by now what claims are the strongest.
