April 19 (Reuters) - Qualcomm Inc, the largest maker of chips used in smartphones, reported 9.6 percent fall in quarterly revenue, hurt by an arbitration decision to pay Canada's BlackBerry Ltd for previously received royalties.
Net income attributable to the company fell to $749 million, or 50 cents per share, in the second quarter ended March 26, from $1.16 billion, or 78 cents per share, a year earlier. (http://bit.ly/2ot17st)
Revenue fell to $5.02 billion from $5.55 billion.
The quarter included a $974 million reduction to revenue, or 48 cents per share, related to the BlackBerry arbitration decision, Qualcomm said on Wednesday.
Qualcomm's patent-licensing practices have come under increasing scrutiny from governments across the world, as well as its key customers.
Apple Inc sued the chipmaker in January, accusing Qualcomm of overcharging for its chips and refusing to pay some $1 billion in promised rebates.
Qualcomm fired back at the iPhone maker last week, saying Apple had breached agreements with the firm. (Reporting by Narottam Medhora in Bengaluru; Editing by Sriraj Kalluvila)
