BRUSSELS (Reuters) - U.S. smartphone chipmaker Qualcomm QCOM.O is set to win “imminent” Japanese antitrust clearance for its $38-billion bid for NXP Semiconductors NXPI.O and gain Europe’s approval by the end of the year with slight tweaks to its concessions, a person familiar with the matter said.

Winning the green light from both competition authorities would take Qualcomm a major step forward to closing the deal and reinforce its fight against an unsolicited $103-billion takeover bid from Broadcom.

The Japan Fair Trade Commission (JFTC) “is expected to clear Qualcomm’s acquisition of NXP imminently,” the source said.

“The European Commission is expected to follow soon.”

The JFTC did not respond to emailed requests for comments sent during out of office hours. The EU competition enforcer, which has set a March 15 deadline to rule on the deal, declined to comment while Qualcomm was not available for comment.

Qualcomm, which supplies chips to Android smartphone makers and Apple AAPL.O, wants to become the leading supplier to the fast-growing automotive chips market via the NXP purchase, the biggest-ever in the semiconductor industry.

To address competition concerns, the company has agreed not to purchase NXP’s standard essential patents and not to take legal action against third parties related to NXP’s near field communication (NFC) patents except for defensive purposes.

It also offered an interoperability pledge which will allow rival products to function with NXP’s products.

NXP co-invented NFC chips which enable mobile phones to be used to pay for goods and store and exchange data.

Qualcomm will make incremental changes to concessions offered to the EU authority last month, the person said.

A similar proposal was also proposed to the JFTC.

Broadcom made its move last week in an effort to become the dominant supplier of chips used in the 1.5 billion or so smartphones expected to be sold around the world this year. Qualcomm has dismissed the offer, saying it undervalues the company.

Broadcom, Qualcomm and NXP together would have control over modems, Wi-Fi, GPS and near-field communications chips, a strong position that could concern customers such as Apple and Samsung Electronics Co Ltd 005930.KS because of the bargaining power such a combined company could have to raise prices.

However, a combined company would also likely have a lower cost base and the flexibility to cut prices.
