   I'm unable to replicate this issue. Could you please provide replication steps, if possible?

   It may have to do with older version of solidity. 0.4.19 specifically
   Try it with this contract

   pragma solidity 0.4.19;
   
   
   contract TrademarkRegistration {
       struct TradeMark {
           string phrase;
           string authorName;
           uint256 timestamp;
           bytes32 proof;
       }
   
       mapping (bytes32 => bool) private trademarkLookup;
       mapping (bytes32 => TradeMark) public trademarkRegistry;
       
       function checkTradeMark(string phrase) constant returns (bool) {
           bytes32 proof = phraseProof(phrase);
           return trademarkLookup[proof];
       }
   
       function registerTradeMark(string document, string author) returns (bool){
           if (checkTradeMark(document) == false) {
               bytes32 proofHash = phraseProof(document);
               TradeMark memory trademark = TradeMark({
                   phrase: document,
                   authorName: author,
                   timestamp: now,
                   proof: proofHash
               });
               trademarkLookup[proofHash] = true;
               trademarkRegistry[proofHash] = trademark;
               return true;
           }
           return false;
       }
   
       function phraseProof(string phrase) constant returns (bytes32) {
           return sha256(phrase);
       }
   
       function getTradeMarkData(string phrase) 
           constant returns 
           (string document, 
            string authorName, 
            uint256 timestamp, 
            bytes32 proof) {
           TradeMark memory t = trademarkRegistry[phraseProof(phrase)];
           return (t.phrase, t.authorName, t.timestamp, t.proof);
       }
   }

   The issue is replicable on methods that require a parameter. I'm working on a fix today!
