The 24-year-old midfielder only put pen to paper on a new contract in Sao Paulo last month, but that has done little to stem the constant speculation that surrounds his future.
Inter Milan have been credited with an interest in signing the South American schemer - who is rated at around £9million - but it's Blues boss Roberto Di Matteo who has been most heavily linked with a move for Paulinho, with regular reports suggesting he could be on his way to Stamford Bridge.
However, Filho insists that Corinthians did not renew the player's contract on the basis of extracting a higher transfer fee, adding that a January sale was completely "out of the question".
"We have renewed his contract and we have adjusted it," the club president is quoted on CalcioMercatoNews.com. "Now it is at a level appropriate for Paulinho and the market.
"We have no intention to sell him, it is out of the question. We have a cycle that lasts until July and we renewed his contract to keep him, not to sell him. We do not want to transfer any player in January."
Chelsea currently sit top of the Premier League table with 22 points from their opening nine games - one point clear of Manchester United and reigning champions Manchester City.
Di Matteo will be determined to maintain his side's promising early season form, and may look to club owner Roman Abramovich for funds to further strengthen his squad in January.
