Oklahoma Federal Defense Practice Areas

Federal criminal defense practice areas for Oklahoma — covering the Western, Eastern, and Northern Districts. Healthcare fraud, tax evasion, RICO, money laundering, securities fraud, federal appeals, and more — reference guides published by John D. Kirby.

Healthcare Fraud Defense

Defense against False Claims Act allegations, anti-kickback statute charges, Medicare/Medicaid fraud investigations, and billing fraud prosecutions. These cases are built by prosecutors well before charges arrive.

Tax Evasion Defense

IRS criminal investigation defense, offshore account disclosures, payroll tax cases, and tax fraud prosecutions. Early intervention before charges are filed is critical.

RICO / Racketeering Defense

Defense against federal racketeering charges under the RICO Act. Complex, multi-defendant cases that turn on conspiracy law.

Money Laundering Defense

Defense against federal money laundering charges, structuring cases, and Bank Secrecy Act violations. These cases turn on tracing every transaction and challenging the government's narrative.

Securities Fraud Defense

SEC investigation defense, insider trading charges, investment fraud, and wire fraud prosecutions. A heavily paper-intensive area of federal practice.

Public Corruption Defense

Defense against bribery, honest services fraud, extortion, and federal program fraud charges. Among the most heavily investigated federal offenses.

Crypto & Cybercrime Defense

Cryptocurrency fraud, darknet cases, computer intrusion, and digital asset investigations. The government is aggressively prosecuting this space, and the technical record usually decides the case.

Federal Appeals

Tenth Circuit and federal appellate practice for Oklahoma-based cases. Not every trial outcome is final — an appeal can overturn convictions and reduce sentences.

Antitrust Defense

Price-fixing, bid-rigging, and market allocation investigations. The DOJ Antitrust Division brings criminal charges, and these cases turn on both the law and the economics.

Qui Tam / False Claims Act Defense

Defense against whistleblower lawsuits under the False Claims Act. Early intervention when you learn of a qui tam filing is critical — these cases often run parallel to criminal investigations.
